Whenever I insert the install disc and restart the computer, it just keeps on restarting forever. Nothing seems to work, be it pressing on the "C" key as it starts up, or the option key (this would actually make the hard drive and install DVD icons appear, but whenever I select the DVD icon, the computer would still just restart..).


There seems to be no problem with the DVD when I insert it in the running computer. The finder window would appear, telling me to restart the computer to start the installation, but then the problem would persist as I start it up.


Should I just order a copy of Snow Leopard or is the problem coming from the computer?

iMac, Mac OS X (10.5.8)

    Is this a gray machine specific Disc, or a retail 10.5.x disc?


    What is the 2z691-****-A number on it?

    It's a gray machine specific, a Mac OS version 10.5.4. The number is 2Z691-6248-A

    Hmmm, I don't find a 21.5" 2.66 Core 2 Duo iMac!??? Is it maybe a 20"?

    Well, it may be a 20", but why all those questions? Is there a recurring problem with a specific model of iMacs?

  • BDAqua Level 10 (122,227 points)

    The reason I'm asking is that gray Discs are machine specific, & on occasion Apple has included the wrong Discs... just trying to pinpoint where the problem is or isn't.

    Oh I see, did you figure it out? I plan on upgrading it to Snow Leopard ASAP, maybe with a different disc I could just reboot it from the disk utility?

    First you need to research all the problems people are having with the higher OSX versions, & make sure you have a bootable clone of what you have just in case.


    then you must get 10.6 if they still have it, install it & update to 10.6.8 so you have the App Store to buy & download the huge 10.8 Installer.


    Snow Leopard/10.6.x Requirements...


    General requirements

       * Mac computer with an Intel processor

        * 1GB of memory (I say 4GB at least, more if you can afford it)

        * 5GB of available disk space (I say 30GB at least)

        * DVD drive for installation

        * Some features require a compatible Internet service provider; fees may apply.

        * Some features require Apple’s MobileMe service; fees and terms apply.


    Which apps work with Mac OS X 10.6?...



    It's been pulled from the online store & Apple Stores, so you have to call Apple to buy it, last I heard.

    Buy Snow Leopard > http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
