    Wow, installed update, disabled AGS and I get a freeze on the first boot.

  • bruleke Calculating status...

    @ chairmo: really? Thats bad news!


    I hope Terry and the others install it and tell us their experiences.

  • chrisby10 Calculating status...

    Didn't work for me either.  I installed the update, enabled automatic graphics switching, and disabled auto login.  beach ball city! 


    I switched from windows to avoid this kind of crap.  I never expected apple to manage their closed hardware/software so badly.  This is unacceptable give the lack of diversity of hardware.

    It takes them five minutes to acknowledge and fix a black screen issue but three months and counting to even acknowledge a BBoD bug affecting logins and automatic graphic switching?


    Well... that's encouraging.

    @chairmo, @chrisby10, @bruleke: Thanks for the info. I read the description of what this update is supposed to do and, frankly, it has sounds like a different problem than the one I/we are having (with Lion Cub SBBoD on login), on my (and others') specific MBP6,2 - GeForce 330M Revision ID. That is, I have never experienced a "black screen" on this machine (except during normal sleep - and no problems waking it up).


    So I do not plan to download this SoftWare Update unless there is some other good reason - like an Apple Advisor insisting on it.


    For the Record: I have reformatted my MBP6,2's HD (750GB) into 2 partitions and reinstalled and configured BOTH Snow Leopard (using my OEM Install disks) and Lion (Using my purchased Install, and updated both to their latest respective patches (10.6.8 and 10.7.2).


    Interestingly, Lion (10.7.2) does not alter my AGS setting - it stays as I had previously set it (either ON or OFF).


    The caveat is that  "the bug" (hard freeze, SBBoD on Lion login), and also an ocasional freeze but no SBBoD when running Lion, does not occur when AGS is switched OFF. So this workaround, previously posted on this discussion, seems to be valid.


    I just need to remember to switch AGS OFF (in Snow Leopard) if I want to reboot into Lion, and then remember to switch AGS ON when I want to reboot into Snow Leopard. I could automate this with an Applescript but at the moment it is not worth the trouble.

    @psykdelia: The tip is a good one - the longer you wait, the better the technology is likely to get.


    One small "counterpoint": I just took delivery a new 17-inch MBP8,3 last week - with Lion installed, of course - and have used Software Update to bring it up to 10.7.2. So far - so good. No major problems have shown up.


    One minor wobble: related to starting up iPhoto. I launched iPhoto for the first time and it asked me if I wanted it to launch whenever I connected my camera.


    I clicked [Decide later]. (no problem) Then I clicked iPhoto > [Quit] - and Lion froze! I had to force Power-Off. This happened twice, but, since then the problem seems to have gone away.


    So waiting for 10.7.5 sounds like a good policy. (Give them enough rope and they'll escape from the gallows).


    Other than that, Lion on MBP8,3 runs quite nicely. But I will post again if that changes - probably on a different discussion-thread.

    The latest update seem to have fixed the freezing issue and some graphical glitches I earler experienced in Photoshop.

    Good luck to you guys!

    @terrymahoney:  I just can't wait no more. My old one is dead now.  Freezing before login whatever I try. And I tried a lot ! Got to buy a new MBP, a 17 one as you did. After these 25 pages, your "so far so good" seems to be the new mood when using an Apple machine... Never had a problem in 4 years. Now, I'll have a feeling of instability when using my MBP. Hope this feeling will vanish soon !  Anyway, my old hard disk seems ok, as written when I do a single-user mode. Hope I can get all the datas that are inside and  paste them to the new one ! Someone will work on this @ my office. So far, so good...

    Browsing on the black screen thread it seems this update has not been totally succesful with that problem.


    Here is the support article, it says Apple will service out of warranty MBP free of charge as long as they are less than two years old.  If true, this is great news for me:


    MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

    • Last Modified: 24 October, 2011

    Apple has determined that a small number of MacBook Pro (15-inch, Mid 2010) computers may intermittently freeze or stop displaying video on the built-in display or on an external display connected to the MacBook Pro. In this situation, you may also see a restart warning message before the video is lost or the display turns black or gray. Affected computers were manufactured between April 2010 and February 2011.

    Products Affected

    MacBook Pro (15-inch, Mid 2010)


    For computers with OS X Lion, v10.7

    Run Software Update from the Apple () menu to update your computer to version 10.7.2, then install MacBook Pro Video Update 1.0. If the symptoms persist after installing the update, select one of the service options below.

    For computers with OS X Snow Leopard, v10.6

    Select one of these service options:

    • Apple Retail Store. Set up an appointment with a Genius.
    • Apple Authorized Service Provider. Find one here.
    • Apple Technical Support. Contact us for local service options. 

    Apple will run a software diagnostic test to determine if your computer qualifies for service for this issue.

    Additional Information

    Note: If your 15-inch MacBook Pro is not experiencing any of these symptoms, you do not need to contact Apple.

    Apple will service affected 15-inch MacBook Pro computers free of charge until two years from date of purchase. Apple will provide further extensions to this program as needed. This worldwide Apple program does not extend the standard warranty coverage of the affected MacBook Pro.

    The video update fixed the login screen lockups I experienced in the past. I used to automatically login to avoid the lockups and use the built-in Intel HD graphic adapter. All is well. Ran several tests restarting, logging out and back in, setting the login prompt when turning on the screen saver and after coming out of sleep mode. Without the update, I would consistently lockup at the login screen within 4 restarts. I have actually been running this update for the past 2 weeks as part the beta program.


    MacBook Pro 15" mid-2010 purchased 10/2010.


    So, don't give up. As the post above mine shows, if your system is one of those actually affected, take Apple up on the other services they're offering if the update does not work for you.

    @chairmo et al.: Thanks for posting the link to TS4088. I have just run Software Update again (it's a small patch), and tested Lion 3 or 4 times, by repeatedly logging in and out of Lion, and switching to Snow Leopard 10.6.8 - and back to Lion (on this dual-boot MBP6,2) - All with AGS ON the whole time. (AGS remains on - not changed by the update).


    I am surprised (but pleased) to say that the AGS ON - SBBoD - Hard Freeze - Force Power-Off bug appears to have gone away. I'll post again if it returns. Cheers to all.

    Reading the knowledgebase article it does seem like this is the patch that was made to address the specific issues we've been having.  While my screen doesn't black out it does gray out with the error they mention on login if I let it beach ball long enough.  (usually it takes a few minutes or longer for that to occur).


    Of course this patch HAD to be released only two days after I send my MacBook into the black void for repair.  Sigh.  Wonder if I can call them to get it back.

    @Terry: look what an user said: "Sadly, I think this update just downclocks the MacBook Pro GPU in order to maintain greater 'stability.' After the update, my OpenGL Extensions Viewer benchmark dropped by about 200fps across the board (OGL 1.x and 2.x tests)."


    Can anyone confirm that?
