Moving from OnyX

OnyX has one build per macOS version; macleanup is one script for macOS 11 and later. You lose its hidden settings and system-file checks, so keep OnyX if you use those. Its cleaning tasks have numbered sections here.

What maps to what

In OnyX	In macleanup
Deleting caches	Sections 5, 6, 19 and 27
Uninstalling applications	Section 21, apps idle for a set number of days
Maintenance tasks	Section 13 runs periodic and needs sudo
Hidden Finder, Dock and Safari settings	Nothing
Verifying system files, rebuilding databases	Nothing

Move across

1. Preview the cache layers as one profile. It includes logs too.

   npx macleanup --profile cache-only --dry-run

2. Section 6 needs sudo. With --no-sudo it is skipped, never half-run.

   npx macleanup --profile cache-only --no-sudo --dry-run

3. Look for what OnyX does not list: data from apps you removed.

   npx macleanup --only 12 --dry-run

4. Run the single section you trust first, on its own, and read the prompt.

   npx macleanup --only 7
