I want to play a proshow cd on my iMac

Most of us, like urself were disappointed to find that Apple had done away with CD/DVD Optical Drive in there newest Models. SO we were left with with the same options as other users having to go out an purchase The New Apple USB Superdrive or go to Otherworld Computing or some other Company to purchase the USB Optical Drive for there iMac. Apple's is $79.00 this is what I bought but you are welcome to buy what you want just make sure whatever you pick will work on your Mac.

Cheers

Don
