Hi After my intel iMac froze when running Snow Leopard, I was forced to restart it, and it turned out the HD was corrupted. But after erasing it and performing repair disk, everything is now ok. But since the failure it refuses to reinstall usually giving the message "an error occured when intalling Mac OS X" For the last few, very frustrating days, I've tried everything I have read on the net: resetting PRAM, checking the HD is set as GUID, erasing and repairing the HD numeous times, performing hardware tests. Even slaughtering farm yard animals. Basically everything. And still it won't install. I really am at my wits end, and to make matters worse, the genius bar here in Tokyo is so busy I can't get a reservation til Friday evening. I'd be incredibly grateful for any help at all. Thanks!
