Snow Leopard | Installation fail?
Hi - I've been hunting through the forum and I apologise if this has already been answered elsewhere, but I couldn't find anything about it.

I have just received my family copy of 10.6.3 Snow Leopard and sucessfully upgraded my macbook. When we tried to upgrade the imac (from Leopard OS) the upgrade seems to have installed ok, but when the machine automatically reboots, I get a white screen with an endlessly spinning loading symbol.

So far we've let it sit spinning like that for 15 minutes and then turned it off (this problem didn't arise with the macbook).

THEN we couldn't get the disk out of the drive (we can do that now!).

Another two attempts to reinstall resulted in the same problem.

Can anyone give me any suggestions as to what might be the issue and how I might resolve it.

This is my first post btw, *waves* nice to meet you :-)

The first thing to do is boot in Leopard and open Disk Utility. Run verify/repair disk and permissions. It's also worth checking the hard disk has a nice chunk of free space and isn't full.

Thank you for this - as suggested, have opened Utility (am back in Leopard) and checked disk and received message that nothing requires to be repaired.

We recently installed an additional memory card in the imac, so we should have sufficient memory.

Do you check/repair permissions too?

Re: memory. Memory/RAM is the fast temporary storage used by the machine when it's in use.

When I was referring to space, I meant the permanent storage on the hard disk. You can see how much space you have on your Mac HD in Disk Utility

Just to verify since you don't post the specs, is the iMac and Intel Mac or a G5?
If it is a G5 iMac you cannot install Snow Leopard, Leopard is the highest OS it will run.
