Freeing up space · Where your space went
Why doesn't deleting files give me my space back straight away?
Short answer: macOS's local snapshots keep holding the space of files you delete until they age out, usually within a day. Storage Studio tells in-use space from held space, and you can release held space now in Local Snapshots.
Because macOS keeps recent local snapshots of your drive so it always has a clean point to back up from. While a snapshot still refers to a deleted file, the space stays taken — held for the snapshot, not for you. Delete more and you still see nothing.
Storage Studio keeps three cases apart so you know which one you're in:
- In use — files are really there; removing or moving them helps.
- Held for now — files are gone and snapshots hold the space; deleting more won't help.
- Released — space your Mac just handed back by itself.
Held space returns on its own, usually within a day, or release it now in the Local Snapshots manager.
