# Should I wait for macOS to free purgeable space, or use Storage Studio?

If you aren't short of room, waiting is fine — macOS releases purgeable space by itself when something needs it, and held snapshot space usually comes back within about a day.

Storage Studio helps when you **can't wait**: before a macOS update that wants a set amount free, when an app refuses to save, or right after moving a large folder when the free-space figure hasn't caught up. Then you can:

- see how much your Mac's own snapshots are holding, and how old the oldest one is;
- release snapshots already backed up, or reclaim an exact amount, in the [Local Snapshots manager](https://storagestudio.us/manual/local-snapshots);
- open **Emergency Space**, which puts space that comes back without deleting anything at the top of its list.

So it doesn't replace what macOS does on its own — it gives you the "now" button when you need one.
