Didn't think of that

I should have done, it was well in my thoughts when mine was looking problematic!

Thank goodness I'm on O2 rather than Newnet 3GB product.

I think that mervt could do with going back to pre 10.6.4 and starting again.

Sheesh!

I wasn't bothered about the size, I never get anywhere near my quota, but I left it until half of Oxfordshire wasn't streaming the World Cup through my exchange

Sounds worth thinking about.

Is it possible to "unwind" an update in OS X if you haven't got a backup?

Actually, I'm not sure that it is, especially if there have been changes to the Firmware. In mervt's case though it isn't clear if the update has worked.

Archive and Install. Personally I'd only try it as a last resort if I hadn't practiced on a few machines beforehand. On second thought, I'd probably clone the installation to my external drive with Carbon Copy and then play with the cloned version.

I used archive and install once, but can't recall what I'd done to need it... worked without a hitch from what I remember.

I did it at some point, very simple.
