Will installing Yosemite disable my internal DVD drive?
I have an Intel 27" iMac with Mountain Lion (10.8.5) on it. I'm wondering if upgrading to Yosemite will disable my internal DVD drive. This happened to my neighbour and she was told by Apple support to use an external DVD drive because it couldn't be fixed. I'm wondering if this is a common problem or an isolated incident. I use my drive all the time for my work.
iMac, OS X Mountain Lion (10.8.5)
