IMac does not recognize external superdrive
I have a IMac, early 2008, 4 Gig of memory and with the latest sofeware updates 10.8.2. The superdrive works sporatically. I purchased an Apple external superdrive. The IMac will not recognize the external superdrive. I have searched the form and the only solution I have been able to find is a technical answer that does not make any sense. If possible, can anyone tell me, in as simple terms as possible, why the IMac does not recognize the external superdrive?
