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

Yep, I have exactly the same problem on my MBP.

In fact, 1 in 2 logins are unsuccessful and the whirling disk of death continues indefinitely, unless I hard reboot the computer. After two hard reboots, it asks at login whether I want to reopen the same programmes as before (Resume, I presume). If I say no, then startup is not a problem.

What I have started to do is to disable Resume at startup by unchecking the box that says something like, "Do you want to re-open current applications on startup" when I shut down. With this strategy, startup works without a problem. I haven't tried the graphic switching thing above yet.

I'm sure many people are having this problem, so why didn't apple fix this bug in last week's software update for Lion?

Apple, please fix this problem...we know you're out there and listening to us...

Same problem here 1 out of 5 succsessuful logins... This is defenitely not acceptable OS X Lion is Freezing and Freezing continuously .... Please Apple fix this BUG ... MacBook pro is i5 2.4Ghz ...

The solution that I have found for my MBP (Mid 2010) is the deselection of the automatic graphics switching. Now I have no freezing and everything works fine. So till the next Lion update that resolves our (MBP Mid 2010 group) problem your MBP will work fine.

Incidentally, I should have said that my MBP is a mid 2009 model and I don't have automatic graphics switching options. Seems like there are more than one causes of the startup problem...

Same login screen problem here with mid-2010 MBP. Also, the computer also decides to freeze sometimes when waking from sleep. All apps just go sluggish, then unresponsive, then dead.

While not being able to use my MacBook Pro 15" mid 2010 core i7 because it routinely freezes has been painful, I am grateful for the ability to discover other customers have experienced the same issue, and mainly also owning the same model. Quite certain Apple will provide a remedy, in time.

Just for the others to know.... My MBP (Mid 2010) had also the same issue. I tried to follow all advises here with no results till I tried the SMC reset. I've had no more freezes since then (hope it keeps that way) Just in case this gives Apple a clue about the solution.

Yep SMC reset worked for me too!

The SMC reset worked for me, but only for a few boots. The problem comes back quickly after that.

I have the same spinning wheel freezing up problem with my MacBook Pro 15" mid 2010 i7. I took it a certified Apple repair place in which they erased the hard drive & re-installed Lion which did not fix it. They then replaced the logic board in it twice (yep twice) which still did not fix it. The MBP was then sent into Apple where they replaced the main logic board a third time, also replaced the hard drive, and then installed Snow Leopard on it before giving it back to me. Guess what, to my surprise it no longer froze up (my eyes rolling backwards right about then). So I then installed Lion back on it only to get the spinning wheel freezing up problem again. Thanks for nothing Apple. 10.7.1 did not work for me either. But thanks to the suggestions in this forum of disabling the switchable graphics which has worked for me.

I fixed my problem on my Mac Mini with the following. I had my USB harddrive plugged in but turned off, after I either unplugged the device or powered it on the problem was fixed.
So guys, check if any usb or other external devices might be the problem causing the lockup. 🙂

Wow! Three logic board changes plus a new hard drive, then back to Snow Leopard...

As a (limited) workaround to this problem, in my iMac I have realized that I don't need to reboot if the login window beachballs. I just push the power button a little until the iMac sleeps; a few seconds later I wake up the iMac and everything will be ok. Weird.

Same here!!!!!!!!!!!!!!! two-three brutal shut downs and then it opens!!

That was the "fix" I posted also. The strange part is it has not done it since the Lion update. Citrix is still unusable so until that is fix, Lion is still an unusable OS
