iMac won't read some CDs
My 2007 iMac (24") will not recognize some audio CDs. At first, I wondered if the CDs in question were dirty, but even some brand-new, first-time-out-of-the-package CDs are not being recognized, while others are.
I'll put the disc in, the drive will go "zerg-zerg" about 10 or 11 times, over about 70 seconds, and then it spits the disc out. Other discs are recognized immediately and ripped to iTunes with no problem.
My mid-2007 iMac has 4 GB of RAM and is running Yosemite. I am using iTunes 12.0.1.26.
iMac, OS X Yosemite (10.10.1)
