iMac 27" 5K Retina does not see USB SuperDrive
Bought a new iMac 5K Retina with 1 TB Fusion drive last week. Today I opened the new USB SuperDrive, also purchased last week,
plugged it into a USB port and it doesn't work.
After sharing my iMac with the Apple Care technician and spending nearly an hour on the phone he concluded that the USB SuperDrive was defective. I took it back to the local Apple Store and they gave me another new one. Took it home and it has the same problem.
When it is plugged into a USB Port on the back of the iMac and an audio CDROM inserted, Finder does not see it, the SuperDrive icon does not appear on the desktop. Disk Utility sees it, but it is greyed out and a dialog opens asking if I want to erase the files on it (guess it thinks it is a rewritable CDROM?) . iTunes doesn't see it. When a CDROM is inserted you can hear it spin up and also some soft clicks. After a few minutes it automatically ejects the CDROM. I tried three different audio CDROMs and a data CDROM. All three audio CDROMS work fine on my stereo.
At the start of my call with the Apple Care technician he said that he had heard of some problems with the USB SuperDrive and the new iMac 5K Retina desktop, but didn't know how to fix it. He had me shut down the iMac, unplug the AC power cord, wait a little while and then restart it. Nothing changed.
I suspect some type of software driver problem. Or, could I have received two defective USB SuperDrives? Maybe the iMac is defective?
I spent several hours moving data files and APPs from my MBP to the new iMac and another couple of hours getting it organized just the way I want it. Sure hate to start over with a new computer. But, I don't want a defective one. If I can't find a solution soon, no choice but to take it back into the Apple Store.
Anyone else see this problem? Any suggestions?
