Hey all, You all seem quite knowledgeable so I was wondering if you could help with my Mac issues... I'm getting incredibly frustrated Had my Intel iMac 20" for a couple of weeks now, and have noticed a few recurring problems. The first one is if I shut down the iMac and then go to turn it on again after a while, it takes a concerning amount of time to even show the apple logo, getting stuck at the grey screen beforehand. I can usually get around this by turning the machine off and starting it again, and I've noticed if I unplug all my USB devices it seems to boot normally. Second problem is after leaving bootcamp to boot back into OSX, the iMac doesn't boot at all. I get a blank screen, and the light on the front stays lit. I left the machine for 15 mins, nothing happenned. I rebooted around 3-4 times before I got any life - and I'd also pulled out the USB devices. Hooked to the Belkin USB hub, I have my iPod and 2 USB printers. Hooked directly to my mac, I have 2 external USB hard drives - one is a Maxtor NTFS 300GB Drive, the other a HFS+ 120GB Icybox. Any idea why this thing boots sporadically? This is nowhere near good enough for a machine that cost me over £1,000.
