PreferenceCleaner 2
PreferenceCleaner 2 is a macOS utility that helps users manage and delete corrupted or unwanted preference files — the configuration data that applications and system components store on disk. It provides a graphical interface to locate and remove these files, along with a PreferencePackager tool for migrating preferences to other Macs and an integrated update manager. Users typically run it when an application becomes unstable due to corrupted preferences, or to clear out unused settings. The app requires macOS 10.15 Catalina or later.

1 suggestionPreferenceCleaner 2's last published release was version 2.0 and there is no clear evidence of development continuing after that point. More importantly, the vendor's website and available downloads do not indicate that a native Apple Silicon build has been created. The current build is Intel-only and will stop running entirely when Apple removes Rosetta 2 in macOS 28 (September 2028) — just over two years from now. There is no direct alternative tool that exactly replaces PreferenceCleaner 2's functionality, though modern versions of macOS have built-in preference-management features and third-party app uninstallers like AppCleaner offer similar cleanup routines. Contact the developer at echomist.co.uk to ask whether a native Apple Silicon build is planned; if the answer is no, consider whether the built-in preference tools in System Settings or an alternative app like AppCleaner would meet your needs before that deadline arrives.
