Using old Mac Mini as optical disc drive for a new one
Thought I'd repost this under my own name:
An update for all those who want to use an old Mac Mini's optical disc drive in a new Mac Mini, which has no disc drive. It WILL NOT work with a firewire connection. The old mini does work as an OPTICAL DRIVE ONLY if you connect it to the new one via USB cable (male to male). It will work both as an OPTICAL DRIVE and an EXTERNAL HD if you connect it to the new mini on an Ethernet network (this through my DSL modem which has three Ethernet ports) or by WiFi. If you keep an OSX system on the old mini you can also use any old apps on that computer via screen sharing on the new one. Hope this helps all who had my problem.
Mac mini (Late 2012), OS X Mavericks (10.9), 16 GB Ram, 2.6 Intel quad core i7
