Understanding Mac Storage

Your Mac's storage holds all your data: documents, photos, apps, games, and system files. Insufficient free space significantly impacts your Mac's speed. This guide covers various methods for checking storage on both M1, M2, and Intel Macs.

Checking Disk Space on Your Mac

Several methods allow you to easily check your Mac's storage:

1. System Information:

   • Open Spotlight search (Command Space), type "System Information," and press Enter.
   • Click "Storage" in the sidebar to view free and total capacity.

   

2. About This Mac & System Settings:

   • Click the Apple menu, select "About This Mac," then the "Storage" tab (availability varies by macOS version). Alternatively, open System Settings, click "General," then "About," and scroll to the "Storage" section.

   

3. Get Info in Finder:

   • Select your Mac's storage drive (usually "Macintosh HD") on your desktop.
   • Press Command I to open the "Get Info" window. View "Capacity," "Available," and "Used" information. If your startup disk isn't visible, go to Finder > Preferences > General and check "Hard disks."

   

4. Disk Utility:

   • Open Disk Utility (Applications > Utilities).
   • Select your startup disk ("Macintosh HD") to view capacity and free space.

   

5. Quick Look:

   • Select your startup disk on the desktop and press the spacebar.

   

6. Terminal:

   • Open Terminal (Applications > Utilities).
   • Type df -h and press Enter.

   

7. Mac Cleanup Program (e.g., MacKeeper): Dedicated cleanup utilities can identify and remove unnecessary files to free up space.

   

Checking External Drive Space

Most of the above methods work for external drives. Disk Utility is recommended for managing external drives, providing options for repair, partitioning, and erasing.

Managing Mac Storage

To manage storage: use a Mac cleanup utility, manually delete unwanted files and apps, transfer large files to an external drive, or enable iCloud storage optimization (System Settings > Your Name > Optimize Mac Storage).

Conclusion

Many options exist for checking and managing your Mac's storage. Choose the method that best suits your needs and comfort level. Consider using a Mac cleanup utility for automated space reclamation.
