    Hi,

    i resolved it by deleting: /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

    and then rebooting in safe-mode and then rebooting regular.

     

    At least it seems so.

     

     

    Edit:

    The Freeze only appeared after being idle for at least 10-15seconds.

    Here is my experience and what worked for me:

     

    My "Magic Trackpad" would not connect this morning.  I use it all the time and was using it late yesterday.  I did walk into the livingroom and was warned it had "Lost Connection".  Even earlier this week I was traveling and when I got home it discovered and reconnected without a problem.  I figured a journey into the livingroom 15 feet away would be okay.  Maybe it was low on battery. This morning nothing I sat down and noticed the TrackPad not working. I tried to Connect using the bluetooth menu but that didn't work, I tried changing batteries and again tried connecting multiple times but it would not.  The Mac showed it in the Bluetooth menu so apparently remembered there was a Trackpad but for what ever reason could not see how to connect.

     

    I read the replies to this post but didn't see any similarities with the Cache files. So I did nothing to my directories.

     

    Instead I fixed by holding the power button (right side opposite the battery hatch) on the trackpad for several seconds (10-15?) it started to flash the little green light at me, then I selected connect again in the Bluetooth menu as I had before but this time it connected. 

     

    Hope that helps someone.

    I guess I resolved the problem by stopping the "Android File Transfer"-Service. I can't  provocate this issue anymore (so far), so I think it's fixed. Maybe there is a problem with the USB-driver or so..

    I recently just reformatted my Macbook pro and my trackpad stopped working after I logged in, I could see the mouse arrow moving around but I could not select by pressing the pad. What eventually worked for me was 1st: Pressing hard on the trackpad and applying pressure all across the surface. 2nd: After pressing on the trackpad surface for a while I found out if I pressed hard enough I could select but it was a pain pressing the **** out of the pad just to make a selection so I went to "Preferences" and then selected "trackpad" and then selected "Tap to click" and it started to work like it use to, but I ended up having to use 3 fingers to select and drag..which was annoying as ****. So I went to "Preferences/Universal Access/Trackpad Options/ and select "Dragging". That worked.

     

     

    Also try: Shutting down computer, plug it in, then start pressing Shift/control/option while pressing the power up button for 15 seconds and when you let go the light on your power cord connected to your Mac should go to green then back to orange, then power up your mac again.

     

     

    Also try: Command+Option+P+R while you power up your mac and wait til it chime 2wice ...then start up again.

     

     

    Hopes this helps....someone, I know how it is...

    I only recently developed this problem with the magic trackpad well after the initial upgrad so I'm not sure what caused it. Anyway, I didn't find this post yet and tried resetting the PRAM, as you recommended, just for hoots and it was successful. Although... I was told many years ago that 7 times was the magic Apple number for resetting the PRAM so that's what I've done ever since. Ok thanks.

    We have those files in common, if that might help anyone else.. Suspect one of those cause the problems then.

    I have been experiencing the same issue as well since upgrading to 10.8.2 on my MacBook Pro w/ RD and after removing "com.google.keystone.deamon.plist" the issue was fixedfor me. 

     

     

    That confirms it! The google-stuff is the one causing problems.

    First, open Finder, select Go menu > Go to Folder, type /Library/Preferences and delete that file. It's deleted as other files.

     

     

    Nevermind.

    My trackpad stopped working this morning. I couldnt get past the startup screen. No matter how i clicked the trackpad. Nothing! Tried all sorts of suggestions from others on web.

    What worked was this.

    I also have a mouse in my carry bag. i tried to get this to work and it came on the screen that the battery was low in the mouse. Changed them and withing 30 seconds or so the trackpad became usable again.

    Didnt make sense really, but i am not too fussed. Stress level is now down again. And macbook working agian.

     

    My message is ...its nearly allways sothing simpler than you think and needs a little thinking time before going off into deeper stuff!

     

    hope this helps some people!

    Thanks so much for this information!!!! My trackpad also began going to sleep just as I was in the middle of my projects after the update... horrendously frustrating! It helped to restart, but when you're using an application like QuickBooks, you don't have all day long to wait for the monster to relaunch!

     

    In my MacBook Pro, it turned out there were hundreds of errors with the iBooks app, which I don't even use. Weird, when I saw the icon for iBooks pop up on my Launchpad screen, I got a strange intuitive feeling about it--"I'll never use that," I thought to myself, and now it turned out to be the source of my problems! I should listen to my gut more often, I think! 

     

    Thanks again for the advice to use the disk utility first aid!
