uk.co.EchoMist.PreferenceCleaner2Helper
PreferenceCleaner is a macOS utility that simplifies the deletion and management of application preference files. Preference files can become corrupt and cause applications or OS components to become unstable, or accumulate unwanted settings. PreferenceCleaner provides a graphical interface to delete preference files safely, and includes the PreferencePackager tool for migrating preferences between Macs. The app is part of the EchoMist software suite and requires macOS 10.15 (Catalina) or later. PreferenceCleaner 2 includes a built-in update manager and uses a privileged helper daemon to perform system-level operations.
AI Recommendation
1 suggestionThis is a launchDaemon helper component of PreferenceCleaner 2, not a standalone app. It cannot be updated separately from the main PreferenceCleaner application. To update the helper to a native Apple Silicon build (if one is available), you must update the parent PreferenceCleaner application itself. Visit the EchoMist website at echomist.co.uk/software/PreferenceCleaner.php, download the latest PreferenceCleaner 2 installer, and run it to replace your existing installation. This will update the helper daemon along with the main app. If PreferenceCleaner 2 currently has no native Apple Silicon build, the vendor will need to release one before macOS 28 ships in September 2028, as Intel-only helpers will stop working on that release. Check the EchoMist website periodically for updates, or use the built-in update manager in PreferenceCleaner 2 if your copy already includes one.
