Tuhi, your storage assistant · What Tuhi knows
Can Tuhi tell me if macOS local backups are using my space?
Short answer: Yes. Tuhi checks how many recent local backups macOS is keeping and how old they are, or says there are none. It offers Open Local Snapshots to reclaim them; Time Machine backups on a backup drive aren't affected.
Yes. Ask and Tuhi checks how many recent local backups (snapshots) macOS is keeping on this Mac and how old they are, or tells you there are none to reclaim right now.
If there are some, it offers Open Local Snapshots, where you can see how much space they hold and which are already backed up, and reclaim them. Your Time Machine backups on a backup drive aren't affected.
