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

Not sure what you meant by "30 minutes for one of the restarts to give the MBP a chance to cool down", but have you done this?

1. MBP is off.

2. Turn on MBP.

3. DON'T TOUCH IT.

4. Let it SIT at the Login screen for at least a few minutes.

I always, without fail, get a freeze at the login screen when I do this. If I have the MBP in my lap at startup and I start moving the mouse immediately, then it's fine. I log in normally, and it seems to be more or less stable. I think this is because if you let it sit at the login screen then it switches to a low power state and there is currently some sort of corner case bug that they didn't test for in this instance.

TL;DR: 10.7.1 is still broken with my mid-2010 MBP

I just followed your instructions and left it for 5 minutes, I didn't even touch the track pad and I still didn't get a freeze. I hope that this is it for me. It does seem that people had this problem in different degrees, ranging form locking up every three or four boot up to locking up almost every time. I was locking up every three or four boot up before I turned off the AGS and that stopped it then.

Glad to hear that it's working for you. I'm curious- What version of the firmware do you have on your MBP? I *think* that's what the "SMC" is when you look at your MBP's system details. Mine is:

SMC Version (system): 1.58f16

Just installed and rebooted MBP with 10.7.1. Still the exact same problem.

Thanks for absolutely NOTHING Apple.

I have the same issue here on my mid-2010 MBP 15" (2.66GHz i7). Either clean installation or upgrading from snow leopard doesn't keep me out of this problem.

Yes, I am running the same version of the firmware.

Same issues.

My work around is to uncheck "Reopen windows when logging back in"

Hasn't locked up when doing this step.

Diabling the automatic graphic switching aslo works as a temporary workaround for me.

But I would love to use my battery at its full!

I found one workaroud is to enable automatic login. It goes right into the desktop fast enough before any potential freeze can occur, and I can keep automatic graphic switching enabled.

Effing ridiculous that I need to do this. Apple really gave us the finger on this, didn't they?

After upgrade to 10.7.1, the issue is still there....

i intalled gfxcardstatus http://codykrieger.com/gfxCardStatus and i chose from integrated anly to give me the max batery life or discrete only when its needed and works perfect and if is chose dynamic switshing i will get stuck at the loging screen.i hope apple fix this bug asap....

Having the same issue too, but I don't have a newer Mac Book Pro - mines an early 2008 model so I don't have the Graphics Switching option. 10.7.1 didn't solve it for me. Looks like I'll be reverting back to SL until this is fixed.

This is absolutely and unspeakably ridiculous. I have this same problem but the solution for me is to turn down my backlight on my keyboard. Literally helps me log in every time it happens. Why in the world would the login screen have anything at all to do with the keyboard backlight.

Well, I thought I was OK with version 10.7.1, and I had turned the AGS back on for the last few days, but I did get a beach ball lock up this morning on the log in screen. I turned AGS off and I hope this will solve it as it did before. By the way, 10.7.1 was suppose to solve the wi-fi issues, but my wi-fi still dies once in a while when coming back from sleep... but I digress, this one is for another thread.

Aha. Well now it makes more sense- I was puzzled as to why you would be fine with 10.7.1 and the rest of us aren't 🙂. I actually got in touch with a very good Sr. Support Rep at Apple and I've been working with him over the past couple days to get a better picture of the problem. I ran through about 20 consecutive boots or so and discovered a pattern where you will only get the lock-up/beachball after a previous *successful* (non-crashed/clean boot) session, which explains why you sometimes won't see it and are able to log-in normally.

The problem though is his engineers that he has direct contact with blamed the hardware. We both agreed that it can't be the hardware if *all of us* are having this problem with the mid-2010 Macbook Pros. So last night we left off with him planning on tracking down a mid-2010 Macbook Pro so that he can produce it internally. Internal support staff has wayyy more credibility than us on the forums. Hopefully he'll be able to find one and reproduce the issue.

Another glimmer of hope: he did mention that there is a *known* issue of getting a black and unresponsive screen after waking from sleep- hopefully it's related (power saving) and they kill two birds with one stone.

I'll keep you guys posted if/when I hear anything else.
