Understanding System Data Storage on macOS

System data storage on macOS can accumulate over time, taking up valuable disk space and slowing down your device. But what exactly is system data?

What is System Data?

System data includes cache files, logs, temporary files, and other system-related data that macOS uses for operations. While some of this data is essential, a significant portion can be safely deleted to free up space.

Why Does System Data Grow?

System data grows due to:

  • Cached app data.
  • Old system logs and update files.
  • Temporary files from apps and processes.

Steps to Clear Up Storage on System Data macOS

Step 1: Check Storage Usage

  1. Click on the Apple menu and select About This Mac.
  2. Navigate to the Storage tab.
  3. Review the System Data section to see how much space it occupies.

Step 2: Clear Cache Files

  1. Open Finder and select Go > Go to Folder.
  2. Enter ~/Library/Caches.

  4. Repeat the process for /Library/Caches.

Step 3: Remove Unnecessary Logs

  2. Delete log files you no longer need.

Step 4: Delete Temporary Files

  1. Open Finder and select Go > Go to Folder.
  2. Enter /var/folders.

Advanced Tips to Free Up Storage
