OS X Lion freezes at login screen + App Store is slow

i know that feel bro. 😟

This issue seems to be solved in the latest 10.7.4 developer seed. The release notes states that one of the focus areas is Graphics, and after I inspected the package manually with Pacifist, I indeed found updated Graphics Drivers + Power Management Kexts for all the graphic cards.

@nadeem97

Are you in a mid-2010 MacBook Pro? How tests freezing issue is going so far.

Thanks for the information.

Do you also know if this issue is still present in OS X Mountain Lion?

@nadeem97 this sounds great! there is a new hope 🙂

My laptop is one of the very unlucky ones described in http://support.apple.com/kb/TS4088. After a long 4 months fight with apple I got it repaired for free back in early January this year. This issue completely went away (which was related to the Nvidia GPU). Three months later this issue, which is freezing on login screen, or very (extremely) rarely during using the computer strated happening. Tracking down the issue it appeared that the issue is related to the Intel GPU in the laptop.

I've completely disabled it using the "Don't Auto switch graphics switch" and it was gone. But I knew it is not a reliable solution, since I do count on the intel GPU to save battery when my Laptop is not plugged in.

10.7.4 has fixed the issue so far, for me. Will report otherwise if it happens. I do believe it is a software issue, unlike the Nvidia one, which was faulty logicboards.

Hope I helped.

Hi!

My Laptop for now freezes at login, is you take a little long to put the password it freezes, and some times, not always, it gives the Kernel panic and i need to shut it down. and restart again.

Another thing, i was i contact with apple, and they testes my computes in one Apple certified center, and after i send some logs that they asked me to do and send and they didn't find any thing. But i'm using the nvidia GT 330M and my computer was bought in october 2010 directly to the Apple website with some modifications, so it was build in October i guess!

The macbook sometimes freezes during the day, but once in month maybe.

What do you think that i must do? they don't find nothing, neither in the logs or in the ACC!

Thanks for the help!

Just another thins i've tried Mac OS X Mountain Lion DP3 and the freezes at the login down't happen, but the others freezes i dind'nt had the os too much time in the mac to see if it freezes!

Thanks again 😉

David

Nadeem: re. 10.4.7, this is very reassuring news. Thanks. 😀

I sounds like they actually know what the problems are, and have created a fix.

I just wish they could push the fix through the Software Update pipeline, so that we don't need to reinstall Snow Leopard while we wait.

Hi David, I like the information from Nadeem97, just before your own post. It sounds like the the public release of 10.7.x will fix our MacBookPro (and other Macs') problems. You can probably wait for the release, later this (Northern Hemisphere) Summer. Or try "the kext fix" documented several times on this discussion thread.

Just a short post to say I am yet another MBP 6.2 (mid 2010) user suffering from login screen freezes. Apple care was really nice and admitted that there was an issue. They recommended using full disk encryption, since the login screen then appears at an earlier stage. I am so much hoping for 10.7.4!

>HOORAY!!! This solved the problem! Here are the steps I took:

>1. Edit the /System/Library/Extensions/AppleGraphicsPowerManagement.kext/Contents/Info.plis t file >according to the values for the 6,2 MacBookPro in the 10.6.8 version of the same file using TextWrangler (as in >image in my previous post).

>2. Move the extension file to the trash and reboot in safe mode (shift key down) to flush the extension cache.

>3. Move the extension file from the trash back to its original place (you'll need to authenticate)

>4. Reboot...and take AS LONG AS YOU LIKE to type your username/password.

I just want to say thank you. This immediately fixed my problem with Lion on the mid-2010 macbook pro.

I wanted a "clean" install of lion on a new SSD. What a mistake that was!

I should have done an upgrade and would have had no issues.

Lucky I hadn't reused the old 10.6.8 drive and I just copied the file from the old install to the lion install (while in safe mode) rebooted and BAM! instantly fixed it.

Look at page 47 of this thread for more details and orignal info on this fix.

YEAH!

Editing System/Library/Extensions/AppleGraphicsPowerManagement.kext/Contents/Info.plist (as described above / page 47 several times) seems to work for me too!!!😍

Nadeem97: how long does it ususlly take for a "seed release" of an update to be released to the Software Update pipeline?

It will be good to see that The Hungry but crippled Lion is not going to gobble up the silly OSXtrich before it pulls its head out of the sand, 😁

Mountain Lion could be arriving in the next few weeks - http://reviews.cnet.com/8301-13727_7-57430910-263/mountain-lion-to-arrive-sooner -than-expected/?tag=cnetRiver
