I'm having to update my version of iTunes, and by default my version of OS X to accommodate my new ipod. It will not work with my current set up.

When updating from OS X 10.6.2 to 10.6.8 via 'Mac OS X update combined' in software update, I get a black screen after instillation. I've heard of others having this problem but haven't seen any clear way of rectifying it that I can understand (I'm not that technically literate when it comes to computers).

The computer seems to run in the background but with no screen image. All I get is a check video cable, which I think is an actual screen message, rather than coming from my desk top.

Is there any work around or direct fix? Thanks,

You should try to repair your hard drive by one of these methods:
Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Let us know the result.

Tried a Safe Mode boot?

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Yes, I started up in safe mode after it happened and performed disk maintenance. There were a few things that it fixed, but the black screen remained. It was then that I reloaded OS X from the Install DVD, but that put me back to the start. So I'm still on 10.6.2.

Try downloading 10.6.8 Combo Updater directly (Not through Software Update system):
Mac OS X 10.6.8 Update Combo v1.1

I haven't tried it that way. I'll give it a go.
