3 of the Best Disk Space Analyzers for Mac OS X

Disk space storage analyzer apps for Mac
It’s often only a matter of time before Mac users wind up seeing the dreaded “startup disk almost full” warning message in Mac OS X, which often leads to a frantic dash around the Downloads folder as users trash unnecessary files to attempt to free up disk space. While there’s nothing wrong with going on a manual mission of tracking down where your disk storage vanished to, there are an entire category of disk space analyzer apps available which make the job easier, offering a visual experience that is quickly scannable and actionable.

We’ll cover three of the best and most popular disk space analysis tools available for the Mac, each of which is either free or offers a free trial version to give a good test run with.

A big thing to remember with using these disk analyzer apps is that if you shouldn’t delete anything without discretion, as they sweep the entire drive and inevitably display system files, system folders, and other necessary components of Mac OS X and apps, along with personal documents and accumulated cruft. It’s a good idea to back up the Mac with Time Machine before using these apps if you’re planning on performing some mass file removal, it’s always better to be safe than sorry and lose files or have to reinstall Mac OS X if you deleted critical system files willy-nilly.

DaisyDisk

DaisyDisk is by far the most attractive storage analysis utility, with a beautiful and intuitive interface that makes finding disk clutter a matter of navigating an interactive colorful wheel. In terms of visualization of your file data, DaisyDisk is superior to anything else available, and it’s also very fast.
DaisyDisk analyzes disk storage space on a Mac in a very attractive easy manner
The free version of DaisyDisk is highly functional and will sweep your drive and allow simple quick access to any files or folders found (right-click on anything and choose ‘Show in Finder’), and you could get away with just using the free version if you wanted to, but if you enjoy DaisyDisk enough and find it to be a helpful companion to your Mac experience, the full version is money well spent.

OmniDiskSweeper

OmniDiskSweeper is great and the interface is quite similar to using the Finder in Column view, making it very easy to navigate to large files and folders throughout the file system hierarchy. The files are shown in descending order by size, so it’s very easy to figure out what’s eating up storage space.
OmniDiskSweeper helps analyze and track down large files on a Mac
OmniDiskSweeper has long been one of my favorite free utilities available for the Mac, and I use it often for my own computer and when trying to figure out what’s eating the disk space of other Macs I may encounter. We have discussed using OmniDiskSweeper before here on multiple occasions, it’s a great tool.

Disk Inventory X

Disk Inventory X has been around on the Mac for quite some time, it is an oldie but goodie. Though the interface could use some updating, the functionality remains high and the app works great for discovering large blocks of data (for example, a gazillion photos or zip archives). Perhaps the only issue is that in modern versions of Mac OS X, files can be assigned to the app they open with rather than their file type, which may lead to some confusion. Nonetheless, Disk Inventory X is free too, so if you decide it’s not your cup of tea you’re out nothing but a few mb of bandwidth.
DiskInventoryX
A significant perk of DiskInventoryX having been around for ages is that it’s widely supported on much earlier versions of Mac OS X, so if you’re working on an older Mac with earlier system software, this may be the solution you’re looking for.

Bonus: The Finder!

If you don’t want to download any third party utilities, or perhaps you can’t for whatever reason, the Mac search function within the Finder is able to find large files in Mac OS X too. You’ll just need to set a minimum file size to look for, and away it goes.
Finding large file size files in Mac OS X search
The Finder search function works reasonably well for this purpose, but for many Mac users they will find one of the above third party utilities to be easier to quickly scan for large groups of files on a drive with.

Where is the Option Key on Mac Keyboards?

Where is Option / ALT key on Apple keyboards
Using the Option key is an essential part of the Apple keyboard experience for issuing many keystrokes, accessing various hidden features, and a myriad of other functions on both Mac OS X and iOS. All Mac and Apple keyboards have the Option key, it’s just not always labeled as such, which is what offers confusion from time to time. It turns out that certain Apple keyboard layouts have the option key labeled as either a symbol, or as the alt key. This often differs per region and per keyboard, and sometimes even on the age of the hardware itself, but regardless of how they look, every Apple and Mac keyboard includes the option and alt key, including any MacBook, Apple external keyboard, Smart Keyboard for iPad, or other hardware keyboards from Apple.
Below is where you can find the OPTION / ALT key on the major Apple keyboards you are likely to encounter. And yes, in case it wasn’t evident; the OPTION key is the ALT key, which is also represented by the funny looking symbol ⌥ on Apple and Mac keyboards.
The Option / ALT Key on European and UK keyboards actually looks pretty similar to Japanese keyboard layouts and many others:
Option ALT key location on Apple Euro and UK keyboards
Option / ALT Key on US & North American keyboards
Option ALT key location on Apple US keyboards
Option / ALT key on iPad Smart Keyboards:
The Option and ALT Keys on Smart Keyboard

The Option / ALT Key Symbol is “⌥”

This is what the option and alt key symbol looks like, it’s kind of like a backslash with a flag coming off of it. It’s admittedly not very obvious, which is perhaps why Apple has been spelling out alt / option on modern keyboards for many markets.
The Option ALT key symbol on Apple and Mac keyboards

Remember: the Option / ALT key is always between the control key and the command key on Apple & Mac Keyboards

That means on new Mac keyboards you’ll have “Control ^” followed by “ALT / option ⌥” followed by “Command ⌘ ”
The lack of a clearly (and consistently) labeled ‘option’ key puzzled a friend of mine recently who bought a MacBook Pro with a European keyboard layout, and that had a Japanese external Mac keyboard included. Of course those keyboards work with other languages too, but the keys can be labeled differently. In those situations, the Option key is labeled as ALT and the strange looking symbol, it is not clearly labeled as ‘option’ as it is on modern Mac keyboards from the US and many other countries. This isn’t totally unusual however, as long time Mac and Apple users will undoubtedly recall that earlier versions of the Apple Keyboard also didn’t label the alt or option key, and simply used the symbol instead, and on some Mac keyboards symbols were used exclusively.
This should be particularly helpful information to international users and IT staff who encounter machines from other regions, and to newcomers to the Mac and Apple platforms as well. ⎇

Check Packages for Expired Certificates in Mac OS X

How to check package files for expired certificates
Many Mac users will download package files of combo updates or other software in order to install them on multiple computers, thereby avoiding updating with the Mac App Store. This is particularly common with Mac systems administrators, where it makes more sense to download a single package update or installer once and distribute it over a network or perhaps install manually through a USB drive. There is nothing wrong with this approach at all, and in fact it’s much more efficient for multi-Mac management, but one potential hiccup arrives when a package installer or update file has an expired certificate, which will prevent the package from installing entirely, a situation that becomes obvious when you get an “(application installer) was signed with a certificate that has expired” error message.

To avoid this situation, you can check package signatures yourself to see if they are valid, if they have expired, or even if they have no signature at all.

How to Check Package Signature Status in Mac OS X with pkgutil

The excellent pkgutil command line utility can easily determine the status of any package signature and certificate. It’s easy to use, so launch the Terminal app from /Applications/Utilities/ and try it out yourself.
The basic syntax to use for checking a package signature status is like so:
pkgutil --check-signature /Path/to/Example.pkg
Hit return and you’ll find out if the signature is valid, if the signature has expired, or if there is no signature at all.
For example, let’s say we have an Mac OS X Combo Update software installer package, a common scenario for sysadmins updating multiple Macs, you could check the status of that packages signature like so:
pkgutil --check-signature ~/Downloads/OSXUpdateCombo10.10.2.pkg
Package "OSXUpdateCombo10.10.2.pkg":
Status: signed by a certificate that has since expired

In this case, the signature for the update package has expired, meaning it will throw an error if usage is attempted.
Not all package installers have signatures however, and while any software update file from Apple will, packages from third parties often do not. For example, this example package installer file has no signature, and should be treated appropriately (i.e. if you don’t trust the source, perhaps reconsider using it).
pkgutil --check-signature ~/Downloads/MysterySketchyInstaller-21.pkg
Package "MysterySketchyInstaller-21.pkg":
Status: no signature

If a package file is dubious, you can verify the code signature and extract the package without installing it with pkgutil to give it a further inspection, or if you prefer to use the GUI then an app like Pacifist offers similar package management tools in a friendlier interface, even if it’s still on the advanced side of things.
Like all good command line tools, you can even feed pkgutil wildcards to easily check multiple packages at the same time, in this example we’ll check the signature of every *.pkg file contained within ~/Downloads:
pkgutil --check-signature ~/Downloads/*.pkg
Package "irssi-0.8.17-0.pkg":
Status: no signature

Package "wget-4.8.22-0.pkg":
Status: no signature
Package "ComboUpdateOSXElCapitan.pkg":
Status: signed by a certificate that has since expired
Package "InstallOSXSequoiaBeta.pkg":
Status: valid
Package "HRFDeveloperTools.pkg":
Status: valid

Wildcards will make quick work of checking certificate status of many different package files, just be sure you specify *.pkg for the process to complete without stopping on a file that is not a recognized package.

How to Remove a Disk from Time Machine on Mac

Time Machine in Mac OS X All Mac users should have regular automatic backups setup with Time Machine, it’s easy to use and ensures that your personal data and entire Mac is recoverable in the event something goes wrong with the computer. Some people go even further and setup redundant Time Machine backups with multiple disks for added data protection. But sometimes you may decide a particular disk drive is no longer needed by Time Machine, and thus you’d like to remove that particular drive from the backup process without disabling all other Time Machine backups. This can be easily done, and all it does is stop backing up to the particular drive in question, it does not turn off Time Machine to other volumes, and it does not delete any of the backups on the removed drive.

Deleting a Hard Drive from Time Machine Backup to Stop Backups to That Drive from a Mac

Note that you do not need to have the drive connected to the Mac to remove it from Time Machine, this process is the same in all versions of OS X:
  1. Pull down the  Apple menu and choose ‘System Preferences’
  2. Go to the Time Machine system preference panel, then scroll down in the drive list to find “Add or Remove Backup Disk” and click that
  3. Click to remove a Time Machine drive
  4. Select the hard drive, disk, or backup volume that you want to remove from Time Machine backups, then click on “Remove Disk”
  5. Select the drive to remove from Time Machine backups
  6. Confirm that you want to remove the drive from Time Machine and stop backing up to the disk in question
  7. Confirm to remove the drive and stop backups to that particular volume from Time Machine
  8. Exit out of System Preferences when finished
The removed drive will no longer be part of the Time Machine backup chain, meaning when it’s connected to the Mac it will no longer trigger the automatic backup process. Additionally, manually started Time Machine backups will also no longer go to the removed drive when it is connected.
Again, this does not delete any of the data from the Time Machine drive, it simply stops backing up to the drive that has been removed. This also does not turn off Time Machine.
If you want to, you can remove the actual Time Machine backup files from the drive in question yourself, or even format the drive to be Mac compatible and wipe it completely clean of any other data. There’s also nothing wrong with leaving the files there if you think you’ll need it again down the road or refer to them in the future.
Regardless, you’ll want to be sure you have some form of backup going to Time Machine or to another service, never let your Mac or iOS devices go without backups!

How to View Live Photos in Messages for Mac

Play Live Photo in Messages for Mac
Live Photos are basically a still photo that comes to life as a short video, they’re a neat feature that can be captured by newer model iPhone cameras, and now the Messages app on the Mac can view these little moments if they’re sent your way.

To have access to Live Photos in Messages for Mac, you’ll need to be running OS X 10.11.4 or later, as earlier Messages versions don’t support the feature in OS X. Aside from that, you’ll just need someone with an iPhone that can take Live Photos to send the Mac one, the rest is pretty simple.

Watching Live Photos in Messages for Mac OS X

  1. In the Mac Messages app, open the message where the sender has sent you a Live Photo, the Live Photo can be indicated by the little icon in the upper left corner of the image
  2. A Live Photos is indicated by the little icon in the upper left corner of the picture
  3. Double-click on the Live Photo within Messages app to open a preview window of the picture, the live video portion will immediately play
  4. Playing a Live Photo in Messages for mac
  5. Re-play the Live Photo by clicking the little “Live” button in the lower left corner of the preview image
  6. Live photo button
Simple, easy, and works with any Mac with a compatible version of Messages app.
You can try this out yourself if you don’t have someone sending you Live Photos constantly, all you need to do is take a Live Photo with an iPhone camera and then send it to yourself via Messages in iOS so that you can view it on the Mac in the Messages client.
This is a nice feature addition to Messages for Mac, since previously the Live Photos either had to be imported into the Photos app or the sender would have to convert the Live Photo to an animated GIF before sending it over to get a similar experience (for the record, I still hope a ‘convert to gif’ option arrives in future iOS versions, but anyway…).

The Mac Hosts File: How to Modify /etc/hosts in OS X with TextEdit

Edit the hosts file in TextEdit in Mac OS X
The Mac hosts file is a system level file located at /etc/hosts which maps IP addresses to host names for Mac OS X networking. Many users edit and modify the hosts file so that they can point a domain to a different IP address, whether for the purpose of local development, blocking sites, or simply to access alternate servers from various apps and system level functions. Most advanced users will edit the hosts file from the OS X Terminal using nano or vim, but for those who prefer to stay within the Mac OS GUI, you can also modify the Mac’s hosts file through TextEdit, or even a third party app like BBEdit or TextWrangler. This offers a more user friendly option compared to going through the command line.

If you don’t have a specific reason to modify the Mac hosts file in OS X, you should not do so. An incorrectly formatted hosts file or improper entry can lead to DNS issues and problems with various internet services. This is for advanced users.

How to Modify the Mac Hosts File at /etc/hosts with TextEdit OS X

This approach to changing /etc/hosts with TextEdit works with any version of OS X. For Mac users who are running OS X 10.11 or later releases, you must first disable SIP protection however, otherwise the Mac /etc/hosts file will be locked when attempting to access it from TextEdit.
  1. Quit TextEdit if it is currently open
  2. Launch the Terminal application in Mac OS X, found within /Applications/Utilities/
  3. Enter the following command exactly to open the Macs hosts file within the TextEdit GUI application
  4. sudo open -a TextEdit /etc/hosts
  5. Hit return and enter the admin password for OS X when requested to authenticate the launch through sudo
  6. How to modify the hosts file in TextEdit of Mac OS X
  7. The /etc/hosts file will launch into TextEdit as a plain text file where it can be edited and modified as need be, when finished use File > Save or hit Command+S as usual to save the changes to the hosts document *
  8. Quit out of TextEdit, then quit out of Terminal when finished
How to Edit the Mac hosts file in TextEdit for OS X
* If the hosts file shows as “locked” and won’t save changes despite being launched through sudo, it’s likely because you didn’t disable SIP as mentioned in the introduction. You can turn off SIP in OS X with these instructions, which requires a reboot of the Mac. This is necessary for modern versions of OS X, though you can choose to edit the hosts file using the command line with nano as described here without adjusting SIP.
It’s good practice to make a duplicate of the hosts file so that if you break something you can easily fix it, though we’ve got the original default hosts file here in case you need to restore it. It’s also a good idea to set plain text mode as the default for TextEdit.
You’ll likely want to clear out your DNS cache after modifying the hosts file, here’s how to flush DNS in OS X El Capitan and modern versions Mac OS and how to do the same in prior releases.
Users can also choose to modify Mac OS X’s /etc/hosts with TextWrangler, BBEdit, or another third party application. The trick is largely the same as Text Edit, still requiring the use of sudo, but changing the specified application name as follows.
Opening /etc/hosts with TextWrangler:
sudo open -a TextWrangler /etc/hosts
Or launching /etc/hosts into Bbedit:
sudo open -a BBEdit /etc/hosts
While the aforementioned approaches work in all modern versions of OS X, earlier versions of Mac OS X can also launch the TextEdit binary with hosts directly from the command line with the following syntax:
sudo ./Applications/TextEdit.app/Contents/MacOS/TextEdit /etc/hosts
That method will not work in the latest releases, however, thus you’ll want to rely on the open command instead.
Know of another trick to modify the Mac hosts file in an easy fashion through TextEdit or another GUI app? Let us know in the comments.

How to Change the Default System Font in OS X El Capitan to Lucida Grande

Change the Default System Font in OS X El Capitan to Lucida Grande
The Lucida Grande font is known for its crisp and obvious readability which makes it a great user interface font, and it rightfully served as the Mac OS X default system font for many years. Then along came Yosemite, where the Mac system font was changed to the generally unpopular Helvetica Neue. Apple has since improved font readability considerably by changing the default system font yet again in OS X El Capitan, this time to a new font called San Francisco. While the San Francisco font is considerably better as a display font than Helvetica Neue, it’s still not quite as readable for some Mac users and on some non-retina displays as Lucida Grande. Fortunately, with a little effort you can change the default system font on a Mac with OS X El Capitan to Lucida Grande again, and return to the classic user interface font.

This app changes the system font, used in menu bars, menus, the Finder, Dock, window title bars, and elsewhere. If you like the system font the way it is now, or don’t even care, you likely won’t benefit from this application.

Replacing the Mac System Font in OS X El Capitan to Lucida Grande (from Mavericks)

  1. Consider starting a backup of the Mac with Time Machine and waiting for it to finish if you haven’t done so in a while, it’s unlikely you’ll have any problems but backing up is good practice anyway
  2. Go here to download the El Capitan Lucida Grande app, it’s free and open source if you feel like poking around the code yourself
  3. Right-click (or Control+Click) on the “El Capitan Lucida Grande.app” file you just downloaded and choose ‘Open’ – this will launch the app beyond Gatekeeper
  4. Choose the “Patch & Install & Clear font cache” button in the launcher app, then enter the administrator password when requested, the admin login is necessary to create a new file in the /Library/Fonts/ folder, which is the system level font directory*
  5. When finished, quit out of the app and reboot the Mac for changes to take effect throughout OS X
When OS X reboots the system font will be changed to Lucida Grande from San Francisco. Here’s a before and after shown as animated GIF, the change is subtle:
Replacing the default system font in OS X before and after
Here’s a still before and after as well, this is what a Finder window and menu bar look like in OS X with the default San Francisco font (the before):
OS X El Capitan default system font of San Francisco
And here is what the same Finder window and menu bar look like in OS X with Lucida Grande font (the after):
OS X El Capitan with Lucida Grande
As you can see, the changes are extremely subtle. This animated gif gives you an idea of just how subtle the change is, with Lucida Grande being ever so slightly bolder, slightly wider, with slightly more spacing, with the result being it’s slightly more readable to some individuals.

Looks Interesting, But How Does this App Replace the System Font?

For those who might wish to understand what this app is doing to replace the system font in OS X: it’s quite simple, the “Lucida Grande El Capitan” app works by creating a new patched version of the Lucida Grande font and placing that system font file in /Library/Fonts/ called “LucidaGrande_modsysfontelc.ttc”. In other words, it’s simply creating a new font file that is recognized by OS X as being the default system font, thus when Mac OS X boots it loads that new system font file version of Lucida grande rather than San Francisco — it does not replace or modify any system files.

The Default System Fonts Are Barely Different? What’s the Point?

Indeed, going from San Francisco to Lucida Grande is much more subtle than abandoning Helvetica Neue for Lucida Grande or for Comic Sans, so if you’ve never thought twice about the system font in OS X El Capitan let alone in Yosemite or Mavericks, you probably won’t even notice the change, meaning this isn’t really aimed at you. But, for users who either just prefer Lucida Grande due to longstanding habit, or because it’s easier for them to read on a particular display, this little unofficial font patch is a nice modification to Mac OS X.
Perhaps in the future Apple will introduce a ‘bold fonts’ option in OS X Accessibility preferences to make default font text easier for some Mac users to read, much like the bold fonts choice in iOS. But that hasn’t happened yet, so in the meantime, if you’re not thrilled with the system font in OS X El Capitan, consider changing that system font back to the classic Lucida Grande, because for many it’s just easier on the eyes and easier to read.

A few known font display bugs

Indeed there are a few text kerning and spacing bugs with the initial release patch, presumably a fix will resolve those issues shortly. The most annoying is likely found in Safari where multiple tabs start squishing the text together in a tab title, here’s what it looks like:
font bug
Again, a future release of the Lucida Grande replacement font will likely resolve that issue. If it’s a dealbreaker, just uninstall it and wait for the time being.

What About Changing the Default System Font to a Different Font?

If Lucida Grande isn’t your thing, there are other options for new default system fonts in OS X El Capitan which use the same basic idea as this app, many of these existed for prior OS X releases but have yet to be modified for El Capitan. Currently, other alternatives are:
* Note that you can also install fonts and modified Mac system fonts in the user fonts folder at ~/Library/Fonts/, but doing so sometimes causes weird font display gibberish that isn’t remedied by dumping font caches in OS X, particularly with dialog and alert windows. Thus, if you’re replacing the system font, go with the root font directory.

How to Uninstall Programs on Mac Including System Apps

How to remove apps from Mac
Uninstalling apps on Mac is as simple as removing any file, but you may wonder how to do that if you are new to Mac. Apple doesn’t allow to remove system apps on Mac easy way, but it can still be done using terminal. We will tell you everything about removing programs from Mac.

How to uninstall programs on Mac

There are three ways to remove an app from Mac that didn’t come preinstalled with OS X, and one way to remove system apps. Those apps you downloaded can be removed from Application folder, Launchpad and Terminal, but System apps can be removed from Terminal only.

Method 1 : Removing apps from Application Folder (won’t work for system apps)

  • Launch Finder on Mac, and click on Application folder
Application Folder on Mac
  • Right-click on any application, and select Move to Trash
App move to trash on Mac
  • Now you will be asked to enter Administrator Password. So type the Password, and Press Enter Key, and the app will be moved to Trash Folder (Mac doesn’t ask for the admin password for some apps)
  • Now launch Trash Folder, and remove it from there

Method 2: Uninstall programs from Launchpad (can’t delete system apps)

Removing apps from Launchpad is like removing it from iOS. However, you should follow first method, because Launchpad doesn’t allow to remove some apps.
  • Go to Launchpad, and click and hold on any app, just like you do on iPhone or iPad. All the apps icon will start shaking, and you will get cross mark on each app you can remove
  • Now click on Cross Mark, and hit Delete (It will be remove immediately, and won’t go to trash)
Delete Mac Apps

Method 3: How to uninstall any program (including system apps) on Mac

If your Mac is running OS X 10.10 Yosemite or older version, you can launch terminal and start uninstalling apps (even system apps). If you are running OS X 10.11 El Capitan, you need  to disable System Integrity Protection first, and then you can use command in terminal to remove system apps.
Note : You are not recommended to remove any system app, and we hold no responsibility if your laptop starts creating trouble. Any removed app will not go to trash folder, and you can’t recover it until you have backup, or reinstall it. So do it on your own risk. Always keep the backup, in case…..
  • Launch Terminal App (Press Command+Space key to, type Terminal, and press Enter to launch)
Terminal
  • Once terminal in launched type following command, and press enter to go to Application Directory
cd /Applications/
Terminal Applications folder
  • Now you are in Application folder, you need to type the command this way to remove any app : sudo rm -rf AppName.app
  • For example : If I want to remove Spotify app from my Mac, I will type the following in Terminal
sudo rm -rf Spotify.app/
  • Now press Enter key, and type your password (will not be visible), and press Enter key again, and the app will be removed
  • When an app name has 2 words, you need to type following way. This is also an example of removing system app (QuickTime Player)
sudo rm -rf QuickTime\ Player.app/
  • Then press Enter Key, type Password, and press Enter

How to Enable or Disable System Integrity Protection on Mac

modify SIP on Mac OS X
OS X 10.11 El Capitan is the most secure Operating System Apple has ever made. It is secured by the System Integrity Protection that limits the apps and users in root level.
Whether you are a developer or a normal user, no one is recommended to disable System Integrity Protection (SIP). If you do so, Malware, Virus or other infected files would get a chance to use this permission to make changes in your system or preinstalled files. This could make your Mac vulnerable and risk your own data and privacy.
If SIP in enabled, you can still uninstall programs on Mac, but can’t remove any system apps or modify system files. If you want to do something like that, you need to disable SIP, and then it can be done. After making changes it can be enabled again, and we will tell you how. If you are using OS X 10.10 Yosemite or older version, you can remove system apps without disabling SIP.
Note : If you don’t know what you are doing, never try it. I will not be responsible for anything happens ahead. Removing system apps or making changes in system files may make your system unstable.

How to check System Integrity Protection Status, Enable or Disable it

  • Shut down your Mac completely
  • Press Command+R key, and then press Power Key to go to the recovery screen
  • Click on Utilities, and select Terminal
Terminal on Recovery
  • Type the following command in terminal to check System Integrity Protection status. By default it is always on
csrutil status
SIP Status
  • It’s enabled as you can see in the screenshot above, and now we will disable it typing the following command
csrutil disable
Disable SIP
  • Now SIP is disabled, and you can restart your computer. Make any changes you want to do
  • After making changes, you can enable SIP again. Shut down your computer, and Press Command+R+Power Key to go to recovery screen again, open Terminal, and type the following command
csrutil enable
Enable SIP
  • Restart your computer, and enjoy enhanced security

Play Playstation 4 Games on Mac (or Windows) with PS4 Remote Play

PS4 Remote Play plays Playstation 4 games on Mac and Windows
Want to play Playstation 4 games on your computer? Now you can thanks to PS4 Remote Play, available for Mac OS X (and Windows PC). The Remote Play app basically allows you to control the Playstation remotely from a computer, streaming a PS4 game from the Playstation 4 itself to the Mac or PC over a wi-fi or ethernet connection, allowing you to play whatever game is in the PS4, except on the computer.

Requirements are pretty straight forward for PS4 Network Play to work; you’ll need a PS4 console updated to the latest version of Playstation system software, a relatively new Mac or Windows PC with decent hardware, a broadband internet connection that is legitimately fast, with good local networking performance as well, a PS4 controller with USB cable, and a Sony account (like you use on the Playstation). Once you meet those requirements, the rest is easy:

Playing Playstation 4 Games on Mac or PC with PS4 Remote Play

  1. Be sure the Playstation 4 and computer are on the same local network and using the same router*
  2. Go here to download the Remote Play app from Playstation.com and install the app on the computer
  3. Enable Remote Play on the PS4 by going to Settings, then to ‘Remote Play Connection Settings’, and choosing to turn on “Enable Remote Play”
  4. Connect the PS4 controller to the computer with a USB cable, then launch the PS4 Remote Play app and login with the Sony ID, the app will search for and connect to the Playstation and the PS4 or game screen will load in a moment
* After PS4 Remote Play has been setup, you can connect to the Playstation 4 remotely through WAN as well, assuming both the home and remote internet connections are sufficiently fast.

PS4 Remote Play should load the game without issue and you’re ready to play it in windowed mode or full screen mode on the computer.

The app allows you to adjust resolution and frame rate as needed through the Preferences, which also may impact performance depending on the computer and local network. If the performance is suboptimal, reducing the resolution can benefit, whereas a fast network should be able to handle 720p gaming at a high frame rate without issue. For best results, be sure the network connection is strong with little interference, as a weak signal on wi-fi can cause performance issues.

If you have any problems with configuration or issues with the general setup, the previously linked Playstation.com article has a few troubleshooting tips, but generally speaking as long as the internet connection is solid it should work just fine with minimal effort.
This is a particularly great option for Mac gamers to have access to a much larger gaming library, and if you already use a PS4 controller on the Mac you may as well go a step further and setup PS4 Remote Play to play the games in Mac OS X as well. Perhaps a similar app will be made available for Playstation 3 and Xbox One?

Make Animated GIFs from Movies in Mac OS X with Drag & Drop Ease

Make a GIF from a movie in Mac OS X with Drop To Gif
Creating animated GIFs out of a movie file or or video usually requires a bit of effort, but now you can convert a movie into an animated GIF on a Mac with drag and drop simplicity, thanks to the aptly named Drop to GIF.

Drop to GIF is a free app for Mac OS X which automates the entire animated GIF creation process, all you need to do is toss a movie file into the app and the conversion begins. The app is both extremely simple and effective, so if you’re looking to make quick work of gif creation using existing movie or video files, it’s an excellent choice to get started.

Making Animated GIFs with Drop to GIF in Mac OS X

Here is how simple the movie conversion process to GIF is:
  • Get Drop to GIF from Github (free) and launch the app
  • Drag and drop any movie file into the Drop to GIF app, or the app Dock icon, to start converting the chosen video to animated GIF
  • Drop to GIF
  • When conversion is finished, look in the original directory of the movie file to find the exported animated GIF
The exported GIF will loop endlessly, and the default settings will pull the frame rate from the video and set that as the animated GIF FPS as well. Users can make changes to FPS, width size of the animated GIF output file, and GIF quality, adjusting these three settings helps to control the file size of the exported GIF, since a large high FPS animated GIF will wind up being a large file by default. To access the settings, just click on the little gear icon in the app.

There’s even a little handy directory watching feature, where any movie file that appears in a watched directory will instantly be converted into an animated gif. As already mentioned, any exported animated GIF file will be saved in the same directory as the originating movie was, so that directory would contain both the origin movie file and the GIF output.
Here are a few example movies that were converted using Drop to GIF, this one is a quick capture from an iPhone movie that has been compressed heavily:

In this example, the original video is a simple screen recording .mov file made from QuickTime and there has been no compression or quality reduction, meaning the file is a bit on the large size:

For users who need more gif creation and movie conversion options, like a timeline and editing tools, a paid app like Gif Brewery for Mac allows you to convert video to GIF and make edits as well, which would perhaps be a better option for more avid GIF makers. But even if it has fewer features, Drop to GIF is an excellent app, and since it’s free there is little commitment to giving it a try and seeing if it works for your needs.
(By the way, if the Github page looks familiar to anyone, it’s because Drop to GIF arrives from the same developer who brought us the excellent simple language text editor ClearText, which is another fun little app for Mac users.)
