Hi Jack, Jack Honeycutt wrote: > Are you saying that you can not boot to the CD? That's right. I should have stated this earlier. Here is what I have: Mirrored door, dual 1.0Ghz Power Mac 512Mb Jaguar (10.2.8) Superdrive 20" Cinema display To recap, I had powered it on for the first time yesterday. It booted just fine. It's amazing how fast it runs. Everything I opened was super fast. I loved it. Then I did a Software Update. That seemed to go great. A short time later, it froze. Rock solid. Nothing worked. I held down the power button to power it off. After that, nothing worked. I tried powering it with the 'option' key held down. That brought it to sometype of base start up. I was able to open the Superdrive and insert the boot disk. Up comes the icon for the CD. All is great up to now. I select the disk and click on the 'Next' arrow, and then the screen goes white with the Apple logo and a spinning disk. And there it sat for at least 20 minutes. Nothing else happens until I power it down. It is now at an authorized Apple repair shop. :( I was so looking forward to using it and the 20" display tonight. In one of the discussion groups, I read that there could be a problem with incompatibilities between firmware level and software level. I find that hard to believe and I am sure that Apple would have had sometype of check for that before doing a software upgrade. > Are you running Jaguar?
