Pearcleaner is a system maintenance utility designed to reclaim disk space on macOS by identifying and removing residual files left behind after software uninstallation. It functions as an application uninstaller and storage management tool, ensuring that configuration files, caches, and support data are purged to maintain a clean system state.
The application distinguishes itself through event-driven automation, utilizing kernel-level monitoring to detect when files are moved to the trash and triggering immediate scans for orphaned data. It integrates directly into the desktop environment via context menu hooks, allowing users to initiate removal processes from the file browser. Users can further refine these operations through declarative path configuration, which defines specific directory inclusion and exclusion rules for scanning.
Beyond cleanup, the utility provides comprehensive software management by tracking installed applications, plugins, and system services. It also includes optimization features that reduce the disk footprint of application bundles by removing redundant language assets and stripping unused processor architectures from universal binaries.
