David Rice: Apple Macbook Pro Freezing when Switching Application with Command+Tab

  • Martin Baker · 2 years ago
    This has happened to me twice in the past week and yes...I have an external display hooked up to my MBP.

    This has just happened on my 9 month old 15" MBP (Core 2 Duo). It's happened a few times, very annoying. The mouse cursor still moves, I can still SSH in, but killing apps does not seem to make them disappear from the screen. I'm going try LiteSwitch X (Cmd-Tab replacement) which has been suggested as a solution/workaround elsewhere...

    Oh crap, me too! MacBook CD, happens occasionally, usually at wake-from-sleep.. :(

    I have the same problem with my macbook, from dec 2006 (I think it was)..

    Here is a thread also, very active - and as of yet, no viable solution..

    I *really* hope Leopard fixes this very annoying problem. Happened last on i macbook yesterday.

    Regarding the external display .. I'm quite certain that it has happened without one plugged in to my macbook ... But when i think about it, it's alot more frequent when using an external display ....

    Oh totally forgot. Check out this thread http://www.joemaller.com/2006/09/19/os-x-gui-lo... where there is a lot of activity as well, and a lot of people encountering this bug ...

    The reply linked to is mine, that i wrote a while back.

    Also have an external screen attached.
    Just very hard to reproduce, well it happens occasionally.
    When working I have been avoiding cmd-tab cause i don't want this to happen when i am in the middle of an edit.
    The error removeDisplayMapping: _CGSUnmapFramebuffer returns -536870206 shows up on both my MBP17 core duo and the MBP 15 core duo. Very annoying. Just been googling since today since I had some time to try figure out why. Use applecare next I guess.

    It's been 2 weeks since I bought [liteswitchx][0] and I haven't had even the slightest crash. Not to jump the gun a bit but I think this has totally fixed the issue.

    The problem that they claim so undoubtedly is caused by third party applications has been fixed by a third party application. Ironic? yes, and I don't mean alanis morissette ironic.
