OS X Lion freezes at login screen App…: Apple Support Communities

OS X Lion freezes at login screen App…: Apple Support Communities. Interesting that also the App Store is slow as well. jmacbookpro has an update.
To everyone’s interest: my MacBook Pro logic board was finally replaced two days ago, and the problem was still there
. So I have been back to the Genius Bar today (again…) with my repaired-but-not-properly-working Mac. Just while the technician was working with my computer, they have received a notification about a new quality program for this same issue.
Those waiting for a software fix, then, wait no more, or wait forever, as it seems that Apple has found something wrong with at least some mid-2010 Logic Boards. It was not Lion’s fault, after all…
So, if you have a Mid-2010 MacBook Pro 15” which experiences a spinning-ball freeze at login with OS X Lion, check Apple’s support page, as they should post news quite soon. You will probably have to take your computer to an Apple Store; then, if your computer’s serial number corresponds to an affected machine, Apple will change your Logic Board for a new revised one (free of charge, even if the computer is out of warranty).
