Defender 2000 and Defender Elite 200 drives not working for MacOS Catalina

Updated on Feb 24, 2026

UPDATE: We have released an update for both the Defender 2000 and Defender Eltie200 drives to allow functionality on MacOS Catalina.  These updates can be located HERE.

We are aware of an issue with our Defender 2000 and Defender Elite200 drives not working for MacOS Catalina. If you own a Defender 2000 or Defender Elite200 user and need to use the drives on Mac, please refrain from updating to Catalina. We are working on fixing this issue and will post a software update for your Defender encrypted drive.
