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

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?

 

Thanks!

MacBook Pro, Mac OS X (10.7)

    @Helmut1969: I agree! I feel that Apple has lost its focus on marketing a GUI that "just works". It's not quite as bad as MS Vista was, but it's definitely up there. Lion will surely get better, but Apple's marketing people have done the company a disservice by releasing an OS that has enough bugs in it that i produces a frustraitn User Experience.

     

    I'm sure it will improve - but it is taking too long. But how do you deal with a problem like this - if your only recourse is to tell your users that if they need stability, they should wait for a while before upgrading? It's a P/R and marketing problem that senior management needs to address and they are not doing it yet.

    BIG thanks to Metalizer...the enable root (which I did this way: http://www.macosliontips.com/tips/enable-root-account-in-mac-os-x-lion.html ) and repair permissions seems to have worked! I'm crossing my fingers...for the first time I could take my time about logging in and didn't get the SBBoD!

    AAARGH I take that back. I wasn't running the test properly. Logging in and out again is not enough; you have to restart. So restart I did, took my time entering my password, and....SBBoD. Same thing twice in a row. The good news, if there is any good news: I disabled automatic graphics switching, and now all is well (three restarts and logins in a row, without the hang), although I'm not happy about the higher draw on the battery. Apple, this is just a bit nuts...

    Forgot to mention that this was a fresh install of Lion...

    Does anyone know if there is a way to control this system pref via applescript? This way those of us with the problem at login could have the script run at login (i.e. after the login screen) to enable graphics switching, then another script on logout to disable it.

    Hello All...

     

    MY PROBLEM IS FIXED !!

     

    Foreword:

     

    I have a 15 inch Macbook Pro 6,2 (Mid 2010) with 256 MB Nvidia GeForce GT 330M.

    After I did an upgrade to OSX Lion from Snow Leopard, I had this SBBoD.

    I did a hard disk wipe out and finally made a clean install of OSX Lion. I didn't work. I still had the same problem.

     

    Finally I did the following:

     

    THE FIX (It worked for me. But I am not sure whether this is any solution):

     

    1. Logged into OSX Lion

    2. Moved the following file into Trash:

     

    /System/Library/Extensions/AppleGraphicsPowerManagement.kext

     

    3. Did a Shutdown.

    4. Started in Safe Mode ( http://support.apple.com/kb/HT1455 )

    5. Logged into OSX Lion

    6. Did a Shutdown.

    7. Started in normal mode. Logged in.

    8. Put the file back from trash in to the same location " /System/Library/Extensions "

    9. Did a Shutdown.

    10. Started again in Safe Mode. Logged in.

    11. Did a Shutdown.

    12. Started in Normal mode. Logged in.

     

    Thats it !!!

    It has been around 14 days that I am using my Macbook Pro logged in several times (Sometimes even tried logging in after waiting for around 30 mins after the login screen appeared). I am happy that I didnt see this SBBoD again. (Hope it never comes back )

     

    Current Situation:

     

    1. No SBBoD

    2. Automatic Graphics Switching option is still ticked ON

    3. Same file at same location. No Editing and messing around with permissions.

     

    This worked for me.

     

    Merry Christmas !

    I can confirm that moving the kext file out, rebooting and moving it back in helped in my case.

     

    What I did (a bit different procedure):

    1. trashing the file

    2. using the laptop normally, incl. reboots and power downs. No safe mode though.

    3. installing the theoretical nvidia patch for mid-2010 macbooks (the link provided earlier in the thread)

    4. being a bit concerned about overheating, i moved the kext file back a few days later

     

    Guess what... freezing at loging never happened again since that time.

    Can it be that silly as moving the file out and in? 

     

    Good luck!

    @Prasi: Great! And thanks for the step-by-step! This is what others with the MBP6,2 with nVidia GeForce GT 330 should do. Other Mac models may vary.

     

    It you have had a working intel-Mac with Snow Leopard - of any recent vintage - that is unstable with Lion, a software or firmware update and/or an absolutely clean install (using techniques to flush kext caches, etc.) is the first thing to try.

     

    The only reservation I have is that we shouldn't need to do these kinds of "back-flips".

    @fortegas: I also agree that - as Apple has acknowledged - it may be a hardware problem related to the nVidia GT 330 - possibly not being properly seated on the motherboard, or something else.

     

    But this problem is identified with other (different) symptoms that do not include the SSBoD with a freeze-on-login. One Apple technician reportedly said that the motherboard replacement is also supposed to fix this SSBoD-freeze. (I don't think it does, and my local Apple specialist store declined to act on the TS4088 bulletin).

     

    Unfortunately, there is more than one potential cause. And a particular Mac may have more than one of them.

    @Prasi Thanks to you, I am having 5th clean login in a row without any beach balls. I have tried every single method in this form including permission repair under root, it didnt work. Your procedure and replacing Lion's GraphicsPowerManagement kext with Snow Leopard's worked for me. Loging in and out seemed stupid at first but it was definitly worth to try. Since it doesnt feel right replacing Snow Leopards kext, I gave your method a try. Thank you again. I have MacBook Pro mid 2010 2.8Ghz i7.

    @Prasi: too good to be true, alas. I ran the sequence as you suggested, and was leisurely about entering my password at login. SBBoD...

     

    btw I've got the MBP 2.66 i7 with nVidia GeForce GT 330

     

    So I'm back to switching off automatic graphics switching, until I can write an applescript to run at login to have it enabled, and another to disable at logout. If it works I'll post it.

    It is interesting to observe some messages here associating the graphcard problem with the freezing and the SBBoD. My Mac is mid 2009, with a 2.53Mhz dualcore processor and it does NOT have a second graphcard as the newer ones, and it DOES freeze at login.

     

     

    So, my conclusion is that Lion is not a mature OS, and Apples should address this problem (the sooner the better).

     

     

    Hope we have a official position soon, or Apple is more interested in maintaining a false image of error free duo (hardware-operating system).

     

     

    I am waiting.

    ... and I agree with that, 100%. Mac OS X Lion 10.7.2 has still not been adequately tested on all of the Mac hardware platforms on which it is expected to run. Even my recent OEM Lion 17" MBP still crashes occasionally. There are (doubtless) things I can do to fix this, but why should I need to do it on a brand new MBP that came with Lion 10.7 pre-installed? I am just sending "System Reports" to Apple, after each forced re-boot.

    Here's a simple script to enable AGS:

     

    tell application "System Events" to set isUIScriptingEnabled to UI elements enabled

    if isUIScriptingEnabled = false then

              tell application "System Preferences"

      activate

                        set current pane to pane "com.apple.preference.universalaccess"

                        display dialog "Please click the \"Enable access for assistive devices\" checkbox at the bottom of the Universal Access pane and run the script again."

                        return

              end tell

    end if

     

    tell application "System Preferences"

      launch -- use "activate" if you want to see it happen

              set current pane to pane id "com.apple.preference.energysaver"

    end tell

     

    tell application "System Events"

              tell process "System Preferences"

                        set AGS_toggle to checkbox 1 of group 1 of window 1

                        if not value of AGS_toggle as boolean then -- to perform the opposite click remove "not"

      click AGS_toggle

                        end if

              end tell

    end tell

     

    tell application "System Preferences"

      quit

    end tell

     

    to make a script that disables AGs, remove the word "not" as in the comment above.

     

    If you paste this into the Apple Script Editor, you can save it as an application and have it run on login (in system preferences/users & groups/login items). To have it run on logout (i.e. so it's disabled for the next time you try to login) you can use http://rsug.itd.umich.edu/software/ihook/

     

    This seems like a reasonable temporary solution that will allow you to continue to use AGS while working but to make sure that it's disabled before shutdown or logoff so you don't get hung up on login. Of course it won't help if your system crashes, but let's hope we're now beyond that....
