Performance & battery · When your Mac feels slow
Will clearing caches with Storage Studio make my Mac faster?
Short answer: Not directly. Clearing caches frees space, which helps if the disk was nearly full, but apps may launch a bit slower once while they rebuild their caches. Storage Studio clears only regenerable cache data.
Not directly. Clearing caches frees disk space, which helps if your startup disk was nearly full — then macOS has room for virtual memory and updates again. But caches exist to make apps faster, so right after clearing, an app's first launch can be a little slower while it rebuilds what it needs.
Storage Studio only clears regenerable cache data that apps recreate automatically — never your documents or settings.
If your Mac is slow and the disk has plenty of space, look at memory or busy apps instead — ask Tuhi. More in Freeing space.
