Free up storage space on your Mac

Use the storage-management features of your Mac, or free up space in other ways.

Optimise storage space

To make more storage space available, use the storage-management features of macOS Sierra or later.

  1. From the Apple menu  in the corner of your screen, choose About This Mac. Then click Storage to see the amount of storage space available for your data.
    About this Mac Storage tab
  2. Click the Manage button.
  3. Choose from the recommendations shown, such as Store in iCloud,* Optimise Storage and Reduce Clutter. Find out more about how to use these features to optimise storage space.

Free up storage space in other ways

  • Delete unneeded files manually by moving them to the Bin and then emptying the Bin. Deleting unneeded music, films and other media can free up a lot of space, as can deleting files in the Downloads folder.
  • Delete unneeded emails in the Mail app. To delete junk emails, open Mail and choose Mailbox > Erase Junk Mail. To delete emails you've moved to the Bin mailbox, choose Mailbox > Erase Deleted Items.
  • Connect an external storage device to your Mac, then move files to that device.
  • Compress files so they use less storage space.
  • Make sure your Mac is using macOS Sierra or later, which includes space-saving features, such as detecting duplicate downloads in Safari; reminding you to delete used app installers; removing old and unused fonts, languages and dictionaries; and clearing caches, logs and other unnecessary data when storage space is needed.

Check your progress

To check your progress while freeing up storage space, rely on the amount of storage space shown as "available" in About This Mac or at the top of the storage-management window pictured above.

Other measurements, including measurements in other tools, may calculate storage space differently, or show storage categories such as Other, Purgeable, Free, Other Volumes, Not Mounted, VM, Recovery or System Data. Don't rely on those measurements to understand how much space is available for your data, or how to make more space available.
