![]() I have read of issues with OWC discs not accepting the upgrade on certain machines, but the problem appears to affect a different brand disc (Aura), and a different year Mac Pro.

Same thing.ġ) When I first downloaded it asked to update my firmware. Waited an hour, then deleted and tried a couple times. Grey bar is about 1/8 of the way through.
