Clear Unity Cache on Mac

Quick answer

Over time, Unity accumulates asset cache, library, packages in ~/Library/Application Support/Unity that can grow to 2 GB – 100 GB. Clearing them often fixes glitches, login loops and frees serious disk space.

Frequently Asked Questions

Is it safe to delete these files manually?

Yes — files in ~/Library/Application Support/Unity are app-generated and safe to remove after quitting the app. Risk level: Safe. macOS or the app will recreate anything still needed.

Will I lose my settings or data?

Manual removal of the support folder resets the app to defaults. To keep settings, back up the location first or use OptiClear's selective cleanup.
