I installed OS X Lion in my Mac Book Pro (Mid 2010) and have two issues:
- Login screen freezes sometimes. "Colored rotating disc" appears, text cursor stops blinking and I can not do anything; I can not click anywere, I can not enter my user name/password... Only option is to hard-reboot the computer, which is not a pleasant thing to do.
- App Store is very slow. It takes about 30 seconds of "rotating colored disc thinking" every time a page has to be loaded!
I first installed OS X Lion via Mac App Store and login screen freezes happened about 50% or more of the times I turned on the computer! Also random freezes happened during computer work. Computer was almost unusable under these circumstances, so I reinstalled OS X Lion by doing a clean install (from DVD). After this clean install everithing seemed to run smoothly at first, but now login screen freezes happen again and Mac App Store is very slow as I explained.
I did not have any of these problems with Snow Leopard. I have checked permissions, and I have not installed too many apps yet.
Anybody with these same issues? Any idea of a solution? Somebody at Apple working to solve these problems?
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).
