Overview of USB Defender

The USB Defender feature in iBoysoft DiskGeeker is designed to manage and control USB devices that are connected to your Mac. It can stop the operating system from detecting and mounting USB drives of unknown origin, protecting your Mac and personal files against potential virus attacks.

Once you decide to enable USB Defender, you need to set an authorization password for later USB drive access. After that, you can set USB Defender preferences for USB drives management and maintenance.

By default, there are two optional USB management modes available. The one requires entering the password for each USB access. The other only allows USB drives added into the list (called Whitelist) can be mounted and accessed on your Mac.

USB drives that are not authorized by USB Defender cannot be identified and mounted by the system.
