How to Free Up Storage Space on a MacBook

A nearly full drive doesn't just stop you from saving files. macOS needs free space for updates, virtual memory and temporary files, so a packed MacBook often feels slow and may refuse to update. Here's how to free up storage on a MacBook using the tools already built into macOS, plus the places where gigabytes usually hide.

See what's using your storage

1. On macOS Ventura or later, open the Apple menu > System Settings > General > Storage.
2. On older versions, choose Apple menu > About This Mac, click Storage, then Manage.
3. Wait for the bar to finish calculating. You'll see categories like Applications, Documents, Photos, Mail and System Data.

Click the info button next to a category to see the biggest items and delete what you no longer need.

Use the built-in recommendations

At the top of the Storage screen, macOS offers a few options:

• Store in iCloud: keeps files and photos in iCloud and only stores recent ones locally. Make sure you have enough iCloud storage first.
• Optimize Storage: removes Apple TV movies and shows you've already watched from your Mac.
• Empty Trash Automatically: deletes items that have been in the Trash for 30 days.

Read each option carefully before turning it on so you understand where your files will live.

Clear the usual space hogs

1. Downloads folder: old installers (.dmg and .pkg files), zip archives and duplicate PDFs pile up here. Sort by size and delete what you don't need.
2. Large files: in the Storage screen, open Documents to see large files sorted by size.
3. Unused apps: drag apps you never use to the Trash. Large creative apps and games can take many gigabytes each.
4. iPhone and iPad backups: old device backups can be huge. Look under iOS Files in Storage, or manage them in Finder when your device is connected.
5. Messages attachments: photos and videos from years of chats add up. The Messages category lets you review and delete large attachments.
6. Empty the Trash. Files you delete still take up space until the Trash is emptied.

What about "System Data"?

System Data (called "Other" or "System" on older versions) includes caches, logs, temporary files and local Time Machine snapshots. Some of it clears itself as your Mac needs space, and a restart can help. Avoid deleting files from system folders manually or using aggressive "cleaner" apps, which can cause more problems than they solve. If System Data is unusually large and keeps growing, it's worth having it looked at.

Move files off your Mac safely

Photo and video libraries are often the biggest items on a MacBook. You can move them to an external SSD or drive, but always keep a backup, because a single external drive can fail or get lost. Our guide to backing up with Time Machine shows how to protect your files before you move or delete anything. As a general rule, try to keep at least 10 to 15% of your drive free so macOS has room to work.
