PreferenceCleaner

PreferenceCleaner is a macOS utility that streamlines the removal of preference files, which can become corrupt or cause unwanted behavior in applications and system components. By providing a simple interface for locating and deleting these files, it helps users resolve stability issues without manually hunting through the file system. An accompanying tool, PreferencePackager, enables users to bundle and transfer preferences between Macs, extending the utility beyond deletion to migration.

The application targets macOS 10.15 (Catalina) and later, with earlier versions supporting older releases back to OS X 10.7. Installation consists of dragging the app from a disk image to the hard drive, and the software includes an update manager to keep the tool current. PreferenceCleaner 2.0 adopts the default shell command for deletions, supports Dark Mode, and omits the previous Dock Tool, while earlier releases added features such as permission checking, Dock adjustments, and enhanced compatibility with various third‑party applications.

Overall, PreferenceCleaner offers a focused solution for managing macOS preference files, appealing to users who need a reliable way to clear or migrate settings without deep system knowledge.
