Hi everyone, been lurking on these forums for a whilst but have now registered. I'm having some serious issues with my iMac for a few months now. Apple were kind enough to replace the entire machine with a new one but im still having the issues - which is now making me wonder whether Apple was to blame at all. I'm getting graphic pixelation on startup (which i don't mind) but whats more serious is the amount of kernal panics. Each time i've formatted the Machintosh HD drive, i've always done a time machine restore... should I be trying without this? Reason I want to use Time Machine (obviously) is because it has all my settings, user accounts and applications. My question is - by NOT using the Time Machine, should it have an impact on the system or not i.e. the graphic pixelation and issues im having? Isn't the whole point of having time machine to save the end-user time? Please advise. Thanks.
