I tried to do a clean install of Snow on my iMac. The installation freezes every time on the page where you choose language. I've had to power it off using the power button after waiting for a gererous length of time for it to unfreeze…..every time. So I’ve given up trying to install Snow. So now how do I get the DVD out? As soon as I power it up, it goes right into the installation process without any option to eject the DVD and of course freezes up on the language page. BTW….I used this same DVD to install Snow on the same computer about 3 years ago. I was tyring to install a clean Snow to give the computer to another family member.
