Hi, I'm quite new to both Mac and Macrumors. I tried to find a solution here before posting, but I didn't find any. I have the latest MBP with the latest Mac OS X (all updates installed). I switched it off yesterday and after turning it on today, a message comes up: "You need to restart your computer...". After turning it on/off, it's still the same. I booted from DVD and run Repair permissions and Repair disk utilities and it did not help. I will be mostly grateful for any help as I don't have any backup yet and need the machine up and running. As I said, I'm quite new to the Macs, so please provide specific step-by-step suggestions. Thanks!
