macOS Ventura or later: Choose Apple menu > System Settings, click General in the sidebar, then click Storage on the right.
Earlier versions of macOS: Choose Apple menu > About This Mac, then click Storage.

Move or delete files
If you have another storage device, such as an external drive connected to your Mac, you can move files to that device. Media files such as photos and videos can use a lot of storage space, so you can take steps such as these:
You can also delete files that you no longer need. For example:
Delete music, movies, podcasts, or other media, especially if it's media that you can stream or download again as needed.
Delete files in your Downloads folder. Open this folder from the Dock, or by choosing Go > Downloads from the menu bar in the Finder.
If you use the Mail app for your email, choose Mailbox > Erase Junk Mail from the menu bar in Mail. Also choose Mailbox > Erase Deleted Items.
If you use your Mac to back up your iPhone or iPad, you can delete old backups.
Uninstall apps that you no longer use.
If your Mac is set up for multiple users, delete users that no longer need access to your Mac. Or ask them to follow the steps in this article after logging in to their user account.
Check the Users folder on Macintosh HD for any undeleted data belonging to deleted users, as well as any shared files that you no longer need to share.
If you don't want to delete certain files, you might be able to save space by compressing them. Then expand them when you need to use them again.
Did you empty the Trash? When you move a file to the Trash, its storage space doesn't become available until you empty the Trash.
System Data and Other are broad storage categories that contain many types of files (both Apple and third-party) that don't fall into any of the other storage categories. The steps in this article apply to all storage categories.
Storing files in iCloud uses storage space in your iCloud storage plan. If you reach your iCloud storage limit, you can buy more iCloud storage directly from your Apple device or make more iCloud storage available. iCloud storage starts at 50GB for $0.99 (USD) a month.
