Hi everyone Last night I picked up a cpu upgrade for my mac and OWC sent me the software needed to install it. Instructions say to use a disk with the dmg, shut down the mac. When turning it back on press the programmers button while it boots and let go when you hear a beep. From there press and hold C to get it to load the disk. I have done this dozens of times so far and it never boots from the disk, in fact I don't even hear it spin up. It goes to OS X and the disk is on the desktop. Am I missing something obvious?
