AppPorts

AppPorts is an open-source macOS utility that moves applications and their associated data to external storage to reclaim internal disk space. It replaces migrated applications with lightweight launchers that preserve familiar icons and opening behavior. Users can continue launching relocated software through Finder, the Dock, or other application launchers while the external drive is connected. APFS mount migration supports suitable application containers while preserving original paths and code signatures. Symbolic links handle compatible folders, developer tools, and custom directories. The application detects missing external drives and broken links. Safety tools include signature checks, application backups, update protection, and restoration workflows. Its interface also provides storage calculations, directory browsing, and migration readiness checks.
