It's really sad for me to report that I've already had to archive and install after only 5 days of having my Mac and using it minimally over those days. My problem was whenever I turned on the Mac, the grey Apple logo would turn into a pixelated corrupted image looking block before the swirling loading icon came up to indicate the system was starting. I called Apple tech support who advised me to try to do an Archive & Install. I did, and this fixed the problem (luckily). Apple tech support advised me that I wouldn't lose annything, which is great, and I didn't - apart from I had to re-install iLife '05 again because it said there was something wrong with it's system files. Now, it seems that I have much less space available on my HDD than I did, and I feel like the system is running slower. Any idea's what I can do to help this? Does the Archive & Install function store a backup of files anywhere I need to remove? Any help would be greatly appreciated.
