I moved an old 2tb internal harddrive out of an 2008 imac 24' into a new 2011 27' imac, and it works fine and has been doing for 6 months. it is simple apple controlling their products to the detriment of the user. snow leopard is perfectly compatible with the new machines. It has nothing to do with incapacity or instability. This is a retail version family pack install dvd. I have booted from this same install dvd once before.Ģ. My gut is telling me that this is an optical drive issue, but I wanted to ask here, since I haven't had any problems with my optical drive before.ġ. It was read perfectly while already booted on the hdd, and it was able to boot from the disc and get me to the clean install menu. I tried using the same disc on my family's iMac, and it worked fine. While the fans are screaming at me, the gray Apple logo just taunts me until I have to force reboot and eject the disc. I can hear the disc trying to be read, but then it dies down, nothing happens for a while, and then the fans start to blast on overdrive. However, when I try to boot from cd (via either holding 'C' while restarting, or opening the Snow Leopard disc options, clicking Utilities, and clicking Restart), I get the gray Apple logo screen. My MBP will read the Snow Leopard dvd fine when it is already booted from the hdd (which boots up perfectly, minus some sluggish-ness, hence the reinstall). I've been trying to reinstall Snow Leopard on my Macbook Pro, but I'm running into a bit of a problem.
