# Why does it say my Mac wasn't ready to let go of space held in automatic backups?

Storage Studio can **ask** macOS to release space held in its automatic backups, but macOS makes the final decision. Sometimes it keeps them — for example, if a backup hasn't been copied to Time Machine yet.

Nothing is wrong. The space comes back on its own, usually within a day. If it's urgent, you can delete individual local snapshots in the Local Snapshots section after reading its warnings.
