Ok, so have you installed 10.5.1 on your new iMac ? Were you having freezing problems before ? Has 10.5.1 fixed it ? Or rather has the iMac graphic firmware update fixed it ?
So far my iMac has not frozen since installing so I am keeping my fingers crossed, but I would love to hear from you if your have experienced a freeze since updating yesterday.
Please drop me a comment on this blog if you have any experience that you can share.
Cheers

Scott will be interested to see how this goes as I'm going to be buying a new iMac soon.
Well so far so good… Will let you know if I have an problems.
Still going… Uptime now 3 days. It looks like this may well have sorted it..
Already had to hard restart twice since updating. It seems that it may have fixed some problems but not all. I'll reserve my judgement for when all the software is updated though.
