Hello Macrumors. I just received my new MacBook Pro Retina more than a week or so. Tomorrow is the last day for its 14 days return. Yesterday I was browsing in Safari and out of no where the computer freezes. So I push the power button until the computer was shutdown. Then I push the power button again. Everything worked. But after that crash, the fans have started to go up 1000 rpm, from 2000 rpm which is default to 3000 rpm without any reason to do so I think. I have tried to reinstall the OS but I just came to the normal login screen with all of my apps just like it was before I did the reinstall. So it seems there was no reinstall? I tried resetting the nvram and pram without any result. So now my beautiful MacBook Pro is up to 3000 rpm where I can hear the fans. Which I'm not supposed to do Any help here? Maybe everything will be fine in Mountain Lion but then I can't return my computer. Oh, and one more thing: Now that I seem to have done a reinstall the computer wants to install 2 updates. 1 Airport-firmware and 1 for the MacBook Pro Retina. Software update 1.0.http://support.apple.com/kb/DL1542?viewlocale=en_US. After I updated I can report back to you if the fan have kicked down to 2000 rpm.
