How to delete purgeable space on Mac
Lacking free space on your Mac? Clear the purgeable space to get extra storage instantly! In this article, you’ll learn about what purgeable space is and ways to remove it. Let's get started.
What is purgeable space?
Purgeable space on Mac is responsible for managing and deleting not essential files and documents when more space is needed. This particular type of storage first appeared on the macOS system with the Sierra update. When you activate the Optimized Storage feature in macOS, you'll notice this new category appears within your storage bar management.
These are the types of files purgeable space targets on Mac:
Ancient user files
iCloud synced files
How to check purgeable space on Mac
To check how much purgeable space is on your Mac, open Disk Utility then choose your disk in the sidebar. You’ll see the amount of space available and purgeable.
Clear purgeable space the easy wayIf you ask me, the simplest and easiest way to clear purgeable space on a Mac is with CleanMyMac X. Its Maintenance module quickly identifies all of your purgeable files and allows you to remove them in a few clicks. I also like to use this app because it's safe to install and use. Here's how it works:
- Launch the application — download the free version.
- Select Maintenance from the sidebar and press View All Tasks.
- Select Free Up Purgeable Space and press Run.
That's it! How simple is that? Congratulations! You've just optimized your Mac and claimed valuable space back!
Remember, regular Mac maintenance is one of the best ways to keep your Mac optimized and running smoothly. I always keep on top of my browser extensions and plugins, unused apps, downloaded files, and old Wi-Fi connections. These items can quickly build up and take up space over time.
Remove purgeable files on Mac manually
1. Clear purgeable space on Mac with Terminal
Because purgeable space automatically clears when your operating system needs space, you can force your Mac to delete purgeable storage by installing or downloading a large file that surpasses the amount of actual free space left on your disk.
So, if you create a large file, your Mac will reallocate all purgeable space to support the installation. Afterward, you can delete the file, and your space will return to a truly free state instead of purgeable space.
That's precisely what we'll do using the Terminal, so let's get started.
Launch Terminal with a spotlight search, Command-space, and type Terminal to open the application.
Type the below command and press enter.
Now, type the following command, pressing enter.
dd if=/dev/random of=~/largefiles/largefile bs=15m
After five minutes, press Control-C in the Terminal window to stop the command.
Type the following command and press Enter.
cp ~/largefiles/largefile ~/largefiles/largefile2
Once complete, enter the same command, this time changing the last number to "3", then when complete, change the last number again to "4," and so on until you see the message "disk is critically low."
Now type in the below command and press Enter:
rm -rf ~/largefiles/
Go to your Trash and empty the contents.
That's it! Check your storage to see the changes to purgeable space.
2. Remove purgeable files with Optimize Storage function
We've got one last tip for you, just in case you're not a fan of using third-party apps like CleanMyMac X, you can also clear purgeable space on a Mac with the Optimize Storage feature, here's how:
Go to System Settings > General > Storage.
Read recommendations to help you manage your Mac's storage space. Enable those you'd like to test.
Check back on the storage overview to see if these have helped reduce your purgeable storage.
3. Clear your cache files
Restarting your Mac can help you delete all cache files and get rid of the purgeable space. But if you are unable to do that due to important tasks in progress, there is a way to delete cache files using Finder.
- Open Finder, then click Go > Library.
- Click Caches and delete files you no longer need.
- Empty Trash.
Be careful not to delete essential macOS files! If you're not sure which files can or cannot be removed, use CleanMyMac X. It has the System Junk module that will help you safely eliminate cache files, language files, system log files, downloads, and user log files. Simply follow the instruction below.
- Launch the app and select System Junk from the sidebar.
- Press Scan; once complete, press Clean.
4. Disable local snapshots in Time Machine
It's quite common that Time Machine local snapshots are the primary space-eaters of purgeable space on Macs. That's why deleting them is on our purgeable space cleanup list. Follow this manual:
- Go to System Settings > General > Time Machine.
- Uncheck the box next to Back Up Automatically.
So that's it, we've reached the end of the article. Hopefully, now you have a good understanding of what purgeable space means and how you can clear it out.
