    I used to face this problem since 10.6.2... until 10.6.6, it did not happen anymore. But after I upgraded to 10.6.7, it's back

    This is an annoying one.

    I bought a new iMac, running 10.6.6, and the keyboard froze on that a few times - I thought it might have been an issue with the hardware. And then it started happening on my 10.6.6 MBP (not frequently, maybe once or twice a month).

    I just asked a colleague here, also running 10.6.6, whether he's had his keyboard freeze up since going to Snow Leopard, and he said yes it happens to him also.

    It affects both the internal laptop keyboard, and externally connected USB keyboards. Unplugging USB devices doesn't help, neither does force-quitting the Finder. Logging out and back in will fix the hang (ie get the keyboard working again), as will rebooting.

    Most of the time, when it hangs, I'm left with the little spaces graphic hanging on the window (the one that appears when you switch spaces using the keyboard) so it seems like perhaps it's related to Spaces.

    And this seems to be a pretty widespread issue. I was just about to upgrade to 10.6.7 in the hope it had been fixed, but it doesn't seem like it has, from reports here...

    Just to mention - I've run SnowLep on this machine since 10.6.0, and I've only had this issue with 10.6.6... it never happened before that.

    To expand this problem a little - I have four sign-in's on a iMac Mini. It only locks out the keyboard on one of them and so far only when using Word. The only way out so far is by restart.

    In addition - to open most anything requires passwords.

    There is also a problem in permissions. Network connected hard drives are only accessible by the first person to open them. If a second ejects the unusable drive and reopens it - he steals the drive and the first person is locked out. Permissions cannot be changed no matter what we try.

    Calling Apple we spent hours on three different levels and finally they suggested go to the close Apple Store with everything (lots of unwiring) and to back up everything. Ever try to back up a 500g drive thru a G3, 10.4.11 and old ports? I don't trust the i

    Wow, this just started happening to me yesterday. I've been using the same Mac Pro without issues for years. I've even had 10.6.7 installed for weeks, without issue.

    Spaces window sticks to screen. I have to manually click on the space I'm on (from the toolbar), to get that to go away. Expose stops working. The keyboard won't type text, although it functions like iTunes back/pause/forward do work. Some shortcuts seem to work too.

    The only thing I've done different within the past 24 hours was install 2 apps, Voila and Little Snapper.

    This issue is driving me nuts!

    Additional info -
    The show character viewer/show keyboard viewer icon is now on my toolbar. First time I've ever seen it..

    Resetting the PRAM and NVRAM seems to have solved the issue for me: http://support.apple.com/kb/ht1379

    I use 16 spaces across multiple monitors, heavy on the expose. I was locking up on just about every space change.

    Hopes this helps someone in the future!

    I have never set up spaces but the keyboard locks up on a constant basis. I was able to have more than one sign in and use the drives on the network but after 10.6. they cannot be accessed because they are listed a no access and cannot be changed. Permissions are screwed up and cannot be corrected. Utility says they are corrected but they do not change.'

    I have found only restarting regains control. Apple accelerated help informed me to bring system (computer, keyboard, drives, and time capsule) into the local store and let them see it.

    Any one else get help yet????

    I am having the same problem, and it is nothing to do with having spaces set up as well. Also the problem is due to something in Snow Leopard as I have completely erased and reinstalled it. Furthermore, I have also reset the NVRAM, again that made no difference.

     

    Come on Apple get this fixed this has been happening for months now, also I am due to buy a new computer later this year and at this rate it will be Windows based!

    FWIW, I didn't start seeing it until I started using Spaces. When I turn off Spaces, the message stops happening. These were the last messages logged before I turned it off. (I added line breaks for readability)

    Seems pretty logical to me that they are connected in some way. I'm not experiencing huge performance hits (only have 4 Spaces) but it is clogging up my Console messages such that if I am trying to troubleshoot something else it becomes impossible to peruse.

    My MBP from 2007 was running Tiger and I wiped the disk to 0 and installed Snow Leopard, but now if I start up not in safe mode, the keyboard isn't recognized, nor is any clicking. The cursor shows up and moves, but nothing else.  (in addition, I get the "blue screen of death" that I've read about at startup and my airport isn't being detected. Oh right. And if the screen goes black from falling asleep, it doesn't wake back up. It's just gone.)

    Hello! I have the keyboard freeze problem too

    For me it appears when I use the computer (iMac4,1) for about 30-45min, then the keyboard stop working and later (if Idon't unplug->replug, because I use EyeTV) the mouse isn't responsive anymore too. But my issue doesn't seem to be spaces related.

    Today there was something strange: keyboard and mouse stopped working as usual but unplug->replug didn't do anything. Then I put it in sleep and I haven't been able to wake it again!! No other solution than unplugging the computer in sleep!!!

    Just wanted to add im also experiencing the same issue. When I use keyboard shortcuts or use the scren edge shortcut with my mouse to activate Spaces, after a while, no real determined time, my keyboard no longer works. Letters, numbers do not work. But the feature keys (screen brightness, volume, backlit keyboard levels) all work but the keyboard letters and numbers do not. When this happens, the Spaces indicator gets frozen on my screen as well.

     

    The only way to fix it is to restart, which is ANNOYING. It's starting to happen at least once a day.

    Resetting the PRAM and NVRAM as suggested by eyecool didn't work for me. Only workarounds that seem to return the keyboard to my control are (1) sleep/wake, (2) bring up login window then log back in, (3) restart (obviously). This is a very frustrating problem!

     

    I'm actually considering stopping using spaces, but I don't know how well I'd function...!

  • the_linguist Level 1 Level 1 (0 points)

    Westmoquette, sadly if my experience is anything to go by this is nothing to do with spaces. I don't think frustrating is quite the word, in my case I am now considering moving back to Windows as it is the only way to get more than 10 minutes use out of a computer.

     

    The only tip I can give is to roll back the Mac to a fresh install of Snow Leopard, that seems to work for me but sadly some software I have requires an updated version of Snow Leopard, or advises it.
