Safe Backup Plus
macOS does not have a standard system for uninstalling programs. However, you can still uninstall Safe Backup Plus by running the following command from a terminal window:

sudo -u root "/Applications/SafeBackupPlus.app/Contents/Resources/uninstall"
This will automatically stop all running Safe Backup Plus processes, unregister Safe Backup Plus's launchd services, and remove all application files from the disk.
