Performance & battery · When your Mac feels slow

\n

Is running low on memory the same as running low on storage?

\n

Short answer: No. Memory is short-term working space for open apps; storage is where files live. Freeing storage won't add RAM, but macOS uses free disk as virtual memory, so a nearly full disk makes memory pressure worse.

\n

No. Memory (RAM) is short-term working space for the apps you have open; storage is the disk where your files and apps live. Freeing storage doesn't add RAM, and Storage Studio doesn't "clean" memory.

\n

They are connected, though: when memory gets tight, macOS uses free disk space as virtual memory, so a nearly full disk makes memory pressure feel worse. Closing a few heavy apps is the quickest relief for memory pressure.
