What Is System Data On Mac?
When you check your Mac’s available storage, you’ll likely find different categories taking up varying amounts of storage. Some will be labeled “Photos” while others are called “Apps” or “Mail.” However, the most peculiar labeling for most people would probably be the “Other” or “System Data” category. Just what is Other in Mac storage and what is System Data on Mac storage? Firstly, let’s clear up a misunderstanding: both “Other” and “System Data” refer to the same category. It’s just that Apple renamed “Other” to “System Data” in macOS Monterey. The label will remain as “Other” if you’re on macOS Big Sur or older iterations of macOS. Now, what is system data on Mac? Simply put, it refers to the category that houses all the miscellaneous files on your device. For example, you can find temporary files, app plugins or extensions, cache files, disk archives, and backups inside system data. As you can see, these files don’t exactly neatly fit into the other categories like Photos or Apps. That’s why macOS lumps them all together as system data – files that help your system run smoothly.

After all, it often takes a lot of space on your Mac — so much so that your storage bloats. Thankfully, there are ways you can delete the files under the category. Below are some of the ways how.
1. Manually Delete Unnecessary Files In The Library Folder
If you need to learn how to clear system storage on Mac for free, then manual deletion is the best method. That’s because it costs nothing to simply dig into folders yourself while deleting files one by one. However, it is more time-consuming and cumbersome to do. Moreover, there’s a risk you might erase important files if you make one wrong move. Nonetheless, it’s a good option to try, especially if your system data folder isn’t too large. Unfortunately, macOS doesn’t make the method as straightforward. You can’t simply go to the Apple menu and click the “System Data” folder in the manage window. It’ll be grayed out and unreachable here. You’ll need to find the Library folder instead. Here’s how:
Open Finder on your computer Choose “Go” in the menu bar Select the “Go to Folder…” option Type “~/library” and hit the enter key
Under this area, you’ll find a large library of folders including your accounts, cache, and cookies. You can carefully dig through these to delete irrelevant files like plugins, .dmg files, and extensions. However, do proceed with caution because deleting folders arbitrarily could damage macOS. To delete unnecessary files, locate a few you’re confident about deleting. Then right-click on the file and select “Move to Bin” to delete it. Do note that these files will remain in your Trash Bin for a month after you erase them. You can easily restore them if you’ve deleted something accidentally. However, you can also go to the Trash Bin and delete these files permanently. After all, what is system data on Mac supposed to do sitting in the trash bin once they’re already deleted?

That’s especially true if you don’t understand what is system data on Mac and which files are important. Moreover, storage cleaners are great at identifying useless duplicate files and unnecessary remnant files. Unfortunately, this does have one big caveat: money. That’s because the most reliable storage cleaners will cost money to use. Some have a recurring subscription fee while others you can purchase for a one-time payment. Nonetheless, these cleaners are essential to clearing up system data on your device without damaging it.
3. Delete Time Machine Backups
What is system data on Mac composed of? One of the biggest space-hoggers that is likely to bloat your system data storage are backups from Time Machine. That’s because, even if you store these backups on external hardware, macOS also keeps a copy within your system. It does this as a safety measure in case your external storage is unavailable when you have to restore files. This makes restoring old backups more convenient for people who need them on the go. However, it also creates a potential for bloating within your system storage. Of course, macOS does delete these backups automatically once your storage capacity is almost full. However, the OS doesn’t always do it properly. Moreover, sometimes you might want to clear the storage before it even gets to that point. After all, too little available space also means your computer’s performance might take a hit. With that said, is there a way to delete Time Machine backups? Thankfully, the process isn’t too complicated. We’ve listed a step-by-step guide below to help you out:
Navigate to Applications in the menu Head to “Utilities” and open the Terminal Once the Terminal window pops up, enter: “tmutil listlocalsnapshotdates” (without the quotations) Hit “Return” to view a list of Time Machine backup files sorted by date Type “tmutil deletelocalsnapshots XXX” — but substitute “XXX” for the name of the backup you want to delete Note: this is usually listed as the date and string of text Hit “Return”
Afterward, you can repeat the last two steps to delete as many files as you desire. You may also monitor how much storage you clear up every time after you remove the files.

Here’s how to find them:
Launch Finder Head to the “Go” menu and press “Go to Folder” Type “~/Library/Application Support” Hit Enter
In the screen that follows, you should find various folders with corresponding labels. If you find a folder corresponding to a deleted app, you can go ahead and delete that folder. Apart from this, you can also clear other files by substituting “~/Library/Application Support” with the following:
~/Library/Caches ~/Library/Logs ~/Library/Containers ~/Library/Cookies
