    I just bought an older iMac off eBay (and it wasn't a box of bricks! yay!) for my daughter. Since it came with Leopard and I have a Snow Leopard install disc lying around, I thought I'd bring it up to the current OS version.

    When I put in the disc, I tried booting with "C" held, but the Apple logo changed to a "no" sign (grey circle with a line through it), and the system booted straight to the desktop as usual.

    After the normal boot process completed, the install DVD opened and I double-clicked "Install OSX". The "Install OSX" dialog appeared for a moment, then a text box appeared over top of the prompt that said "Mac OSX Snow Leopard cannot be installed on this computer." All I could do was quit.

    I opened the Install Log (Command-L), and it says this:
    Code:

    I'm at a loss -- as you can see, the "FailureReason" is an empty string. I rebooted holding Alt (it's a PC keyboard...), chose the install DVD, and after a while, it came up to a very similar screen with a similarly-worded popup (this time in a modal dialog rather than a simple text box), with the only options being "restore from time machine backup" or "reboot".

    Is there something strange with my install disc? Is this computer (identifies itself as "iMac5,1"; I think it's this) incapable of running SL? AFAIK I've seen people post elsewhere that they have this exact model and they identify their OS as SL, so I don't think that's it. The install disc says "Mac OS version 10.6.2 / Disc version 1.0", then has what looks like a part number, if that makes a difference.

    Yeah there is something wrong with your install disc.

    I had the the same problem and it took me for EVER to figure it out. And it was a replacement disc from APPLE no less.

    All I ever got was the same message you got.

    You need to first use the original discs that came with the Computer.

    Mac OS Version 10.4.7/AHT version 3A112/Disc version 1.0/2Z691-5883-A There are 2 discs - the first is labeled iMac MAC OS X Install Disc 1 and the second is iMac MAC OS X Install Disc 2.

    Uh-oh. As I said in the OP, this was an eBay buy -- shipped with the core computer only (hence the PC keyboard). It shipped with a fresh install of 10.5.something, now running 10.5.8 (maybe after a software update? my wife did some of the setup).

    Do I need to borrow some old install discs, roll back to 10.4.7, then try to update using the SL install disc I have now? Should I contact Apple and request a replacement SL disc? Is there any way I can "test" the SL disc I have to see if it is in fact hosed?

    Unless you have a retail-purchased Family Pack of Snow Leopard you are committing copyright infringement: you have a license for one (1) install only.

    Also unless your SL DVD is a retail copy (i.e. not shipped with a new Mac) this won't work: restore DVDs are locked to only work on the hardware they ship with to prevent this sort of casual piracy.
