What is System Data on Mac?
System data on Mac refers to the files and data essential for the proper functioning of the macOS operating system. It helps maintain the stability and performance of your Mac by allowing the operating system to run smoothly and efficiently.
With macOS Ventura update, Apple has introduced changes to the storage categories. The Other storage category has been replaced by a new tab called System Data. Additionally, there is a separate tab called macOS that encompasses all files and data related to the macOS system.
So, what exactly does the System Data tab include? Here’s a list:
Storage Category | Description |
---|---|
Application leftovers | Files that stay in the system even after you uninstall an application |
Temp files and cache | Cache files used by apps, browsers, and the system |
Disk images | Installer files for applications |
Plug-ins and extensions | Tools used to customize apps and web browsers |
In essence, System Data encompasses all those items that do not fit into the macOS category. This includes archives, miscellaneous files, and various other elements that contribute to the overall storage usage.
It is important to note that deleting or modifying system data without proper knowledge or expertise can cause serious issues with Mac’s performance and stability.

Below, I’ve shared how to clear the browser cache on Safari, Google Chrome, and Firefox.

6. Remove Old Time Machine Backups
One of the simplest methods to clear system data on a Mac involves removing Time Machine backups. Surprisingly, even though Time Machine backups are typically stored on external or network drives, macOS also maintains a duplicate copy of the backup on the startup drive.
Ideally, macOS should automatically delete Time Machine backups when the Mac’s storage space is limited. However, this may not always happen as intended. So, if you wish to delete system data on a Mac by removing Time Machine backups, follow the steps below.
Keep in mind that this action will erase the local copies of your backups. So, don’t do it if you may need them in the future.
- Open Terminal from the Utilities folder in Applications.
- In the Terminal window, type the following command and press Enter:
sudo tmutil delete /path/to/backup
Replace /path/to/backup with the actual path to the Time Machine backup you want to remove. For example, if the backup is located in an external hard drive called BackupDrive, the command would be:
sudo tmutil delete /Volumes/BackupDrive/Backups.backupdb/ComputerName/YYYY-MM-DD-HHMMSS
Replace ComputerName with the name of your Mac and YYYY-MM-DD-HHMMSS with the specific backup date and time.
- You’ll be prompted to enter your admin password. Type it and press Enter.
- Terminal will start deleting the Time Machine backup. This process may take some time, depending on the size of the backup.
7. Clear Application Logs and Support Files
Applications generate numerous files that contribute to enhancing your experience while using them. However, when you uninstall an application, there is a possibility that residual files associated with the app remain on your Mac.
Here’s how you can check and clear application logs and support files on Mac:
- Open a Finder window.
- Click Go in the menu bar and select Go to Folder.
- In the dialog box, type the following path and press Enter:
~/Library/Application Support
- In the Library folder, look for folders related to specific applications or developers and delete them if you no longer need the associated logs and support files.
8. Clean Up Your Downloads Folder
The Downloads folder on your Mac is often a repository for files and documents you accumulate over time. From downloaded applications and images to PDFs and archived files, it can quickly become cluttered and disorganized. Cleaning up your Downloads folder helps you regain valuable storage space and a more streamlined digital workspace.
Here’s how to delete downloads on your Mac:
- Open the Finder application on your Mac by clicking the Finder icon in your Dock.
- Navigate to the Downloads folder on your Mac. You can find it in the left sidebar of Finder.
- Select the files or folders you want to delete. You can select multiple items by holding down the Command ⌘ key and clicking each item.
- Move the items to the Bin by pressing Command ⌘ + Delete on your keyboard or dragging the selected items to the Bin icon in the Dock. You can also right-click the selected files and select Move to Bin from the context menu.
- Once you have deleted the items, they will be moved to the Bin. To permanently delete the items, empty the Bin by right-clicking the Bin icon and selecting Empty Bin.
Be careful when deleting downloads on your Mac, as they will be permanently deleted once you empty the Bin.
9. Browse System Folders
Another effective method is to investigate the specific files designated as System Data. Anything stored within your Mac’s System or Library folders falls under this category. To explore these folders, follow these steps:
- Open a Finder window.
- Click Go menu in Finder and select Go to Folder.
- Now, paste the following paths individually:
/Library
/System
~/Library
~/System
- Navigate through the subfolders within each path and press Command + I to access the Get Info window, where you can assess the data size.
Exercise caution if you decide to manually manage System Data and avoid haphazardly deleting cache files or folders.

To optimize storage on your Mac, you can follow these steps:
- Open the Apple menu in the top-left corner of the screen and select About This Mac.
- Click More Info.
- In the new window, click the Storage Settings button.
