Hello, I’m using a WD 3TB My Book for Mac with a Santa Rosa (2007) MacBook Pro running OS X 10.11.1. I’ve been trying to setup the auto unlock feature in WD Security, so it will automatically unlock the drive when I’m logged in, but every time I make the change it doesn’t take. When I reopen WD Security the auto unlock feature is disabled again. Any ideas on how I can resolve this?
Have you tried disabling the security and setting it up again to see if this helps?
I just tried that, same result unfortunately.
