I have replaced the Superdrive in my 2012 MBP 13" with a second hard drive. The Superdrive is now in a external USB case. I have no problems by using the drive with data disc, like games or music disc, but I can’t play video DVDs via the DVD Player app, I always get a error message. Worse I can not rip DVDs via Ripit.app, because also with this app, I get error.
The Superdrive seems not the problem, because attached to my 2012 mini without an internal drive, it works just fine.
Can I solve this problem?
