I bought a Samsung SE-506CB off Amazon which according to the literature should be compatible with OSX 10.4.6+ (I'm running 10.10.3 on my late 2014 iMac). The drive can't be seen under system information or finder. The drive is powering up (USB) and looks to be reading disks but the device can't be seen by the Mac (I've tried bluray, DVD, the install software disk etc). I've spoken to Amazon who are organising a return and refund. According to the net it should be as simple as plug and play so obviously somethings not right (no problems with my Apple Superdrive). I'm still after a bluray drive, can anyone recommend one for my Mac? Ideally I'm after one that is compatible with OSX lol. Any recommendations?
