Are the Defender drives supported on a Mac computer?
Yes, the F100, F150, F200, H100 and H200 are fully supported on Intel based Mac platforms running OS X 10.5 and up. For Mac OS X 10.6 and OS X 10.7, a firmware update may be needed, for early devices. Contact support for more information. Units with firmware Version 2.2 or higher do not need the update.
The Mac can store un-encrypted data on the F50, but the encryption software of the F50 is not Mac compatible.
