Aperture Media Disk Constantly Ejecting from new 10.8 system.
I just got my late 2010 i7 iMac back from the apple store. It has a fresly installed version of 10.8 on it. I brought it home and have been trying to install Aperture 3.0 on it (I still have the media disk with serial #). Every time I insert the disk to the computer it just ejects it.
If I put other dvd's or cd's in, they are read fine and mount properly.
If I put the Aperture disk in my Macbook pro (running 10.7) it mounts fine and is read properly.
I can't find anything on line that shows similar behavior.
Has anyone seen anything like this before?
Any suggestions would be much appreciated.
