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

Same problem here. if i`m fast at the login page I can login otherwise it freezes. only turning off the automatic change of graphic card mode helps. macbook pro 15 from september 2010. installed the osx update some days ago. didn help.

Disabling graphic switching solved this issue

MacBook Pro 2.8Ghz i7, 8GB ram.

how do I do that?

same issue here MBP mid 2010 i7 8gbRAM, freezes again and again ... when finally got in, I switched automatic graphics off and seems to solve the problem (so far...).

This problem could be avoided if you UPGRADE directly from Snowleopard ... and not doing a clean installation.

how long is going to take to release a fix???, kind a disappointed.

How could this problem be avoided if you upgrade from Snow Leopard?

Also, everyone- please quit reffering to turning off AGS as a "solution". It's a "workaround". It does not even come close to solving the problem. This model was never designed to run with the discrete GPU on 100%. It gets extremely hot and the battery life blows.

No Apple technicians or engineers read this board. The only way to get a fix is to call Apple support. You get a free support session with a new purchase of Lion- USE IT.

Actually, this model of MBP will get very hot whether the AGS is on or off and yes it was designed to run with GPU at 100% if you want to switch AGS off.  It does reduce the battery life running AGS off.  I think you are absolutely right to say that it is not a "solution", but a "workaround".  The AGS switching was a selling feature of that model of MBP that we don't have access to anymore and that should definitely be patched. 

Me being an idiot, I decided to install Lion again and been having problems sense.  Turning off AGS helps but does not solve the problem as I continued to have that issue.  I got so frustrated, I took it into the Apple store and told them everything.  He took a look at this forum and was like "oh sh@7".  They've had my MacBook for 3 days today.  Hopefully I hear something today about it.  If they can't fix this issue, they need to upgrade us to the 2011 model that does not have the Nvidia graphics adapter causing this issue.  Spending 2k on a laptop with AppleCare, we should not have these issues.

@Carl - if you have a MBP prior to 2010, you might want to try what someone else suggested to me. It's somewhere in this forum...at shutdown, uncheck the box that says reopen all windows on startup. Should fix the problem, but you have to remember to do this every time you shut down the computer. Works for me anyway. Let us know if it solves the problem with your MBP.

@PA - that only helps the issue but doesn't solve it.   I've done that a few times and every now and then I can't even get past the login screen.  Someone else mentioned an upgrade solves the problem.  I've cleaned installed twice and upgraded 3 times and have ran not the issue ever time.  I've also installed my SSD and had the same exact issue.  We can all agree it's a lion issue with our graphics card considering no one was having this issue with Snow Leopard. 

Adding my voice to the list of people with the beach ball of death in Lion. I have a MBP i7 with 4GB Ram purchased in August 2010 with the High Res screen. I first tried unticking the reopen apps on restart and that helped (locked on up 3 out 4 restarts with that ticked) but still had occasional lockups. I have now turned off AGS and hopefully that will fix my problems also. I also have a MacMini with a Dual Core processor that was purchased in early 2009.  I expected I would have more problems with it running Lion, but apart from it being slightly slower, it runs flawlessly.

Something I'm curious about:

I think it's pretty clear that 99% of us have the Macbook Pro mid-2010, either i5 or i7... but do all of us have the High-Res screen upgrade? That could explain how it got missed during QA. I would like to think that Apple would test Lion against at least one configuration of every release of Macbook Pro before the 10.7.0 release.

So in other words- any of you out there have the standard res mid-2010 Macbook Pro?

mikeev is right!

Please use the 50day free support from Apple and open a case ID and refer to this thread.

This is the only way to get more attention on this on apple side.

regarding High-Res screen upgrade: I have the standard resolution 1440×900

@2good2btrue:

I started with an upgrade from snowleopard and had the same issue, after that I did a clean install.

Both ended up with freezing login screen on my 15" MB Pro.

I do not have any issues on my other 13" old intel core duo MB

Switching off "automatic graphics switching" (AGS) really works, but after a later restart i got the login freeze again, and noticed that AGS had been checked again! How do i get AGS to remain unchecked?? AGS seems to revert to on somehow.

Switching on auto login also helps avoid the login freeze.

hi guys

Initially, switching off "automatic graphics switching" AGS worked for me. Switching on auto login also works but i would think it will only skip the login problem but there might be hangs when playing games or something that trigger the switch.

Recently i read somewhere else about  nvidia drivers being corrupt, then suggesting installing CUDA drivers as a workaround, so i went here http://developer.nvidia.com/cuda-toolkit-40 and downloaded MAC OS developer drivers ( download )

Then i switched on "automatic graphics switching", i was then able to login even after waiting about 2 min in the login screen. I will reply if i find a problem again.

I still think there is something weird with the issue. It seems it has to do with the switching itself but is not corruption, it is a plain bug. The nvidia driver itself must be working otherwise disabling automatic switching shouldn't have help... also i am not sure CUDA will overwrite mac os driver.

Unless someone else is willing to do a reinstall and then installing CUDA drivers, we can't verify it solve the issue, could we?

i also need to call apple support to at least report this info

regards

BTW, MBP mid 2010 15", i5, with high resolution anti glare upgrade. default nvdia card for that model (256 MB i think...)
