Hi All- Just bought a new 2019 iMac i9 8 core retina, pretty much maxed out. Don't have it yet. So, I need to buy an external cd/dvd superdrive, I have many reasons but not point of this post. I have eliminated the Apple right off because it isn't even USB 3.0 where many aftermarkets are. As of now I'm looking at the OWC "Mercury Pro" for ~$69.00 or the OWC "Mercury Pro Blue Ray" for ~ $130.00 yet not sure what the difference between these two are. Leaning toward the $70.00. I assume this new iMac will not recognize any external optical drive since it has no capabilities to play optical media. Do I need to buy software to start with, so the external drive is recognized? I want read/write capability on CD for music, I do video editing on FCPX & would like to burn my movies onto a DVD (I think this is possible) - don't know if video could be burned in blue ray? I read the new iMacs do not recognize Blue Ray in any sense - so be it, I'm stuck with this new iMac. Looking for recommendations on CD/DVD superdrive and software- if needed to run it. Thanks for any suggestions !!
