Please i really need some help

ok so


i updated the software on my macbook using software update

after installing i restarted the computer.

and this happened.

- the start-up screen took an long time. (a lot longer than usual)

- the keyboard was completly unresponsive.

- the trackpad worked, i was able to move the cursor around the screen, and wake the computer from sleeping but not able to click or select anything. (making it pointless)

- the only working part to my laptop was the power button.


so basically i could turn my computer on

move the mouse around the screen, but not click or select anything or use the keyboard in anyway.



i tried to fix the computer by

- re-booting by holding down the power button. i tried this over 8 times, waiting a while after each attempt before restarting the device.

- force quitting, that didnt work because the keyboard didn't.

- with and with out power adapter.

- using a remote keyboard and mouse, and a USB keyboard and mouse, did not work.


but all failed!


please any help would be greatly appreciated.

    First things first. What MacBook model do you have? Which version of OSX are you running?

    I just got the same problem. Track pad and key board lockup after software update on 10/9/2011. Firmware was updated and notes in firmware update referred to keyboard issues. I should not have ran the update as I had no issues but I trusted the updates from Apple. Now I do have an issue and have update remorse.


    Macbook OSX version 10.6.8, 1.83 GHz, Intel Core 2 Duo, Memory 1GB, 667MHz, DDR2, 160GB HD


    I now notice that the track pad will work after I removed the battery and replaced. But when I open Mail it locks up. Trackpad and keyboard are fine so far on all programs but when I open mail, immediately it locks up.


    Never did this until the firmware update yesterday.




    UPDATE: I just found this thread and it solves the problem. https://discussions.apple.com/message/16161031#16161031

    MBP early 2008 here (purchased late fall 2008 as closeout)


    Experienced the typical trackpad/keyboard issue and read through this and other threads.  Just before my Applecare ran out last fall I had the Apple Store replace the Flex cable.  All seemed to work well until recently when the problem returned.


    I thought it was related to heat since it seemed to happen after the unit was in use for a while but now it can happen even a minute or so after waking from sleep or even on start. 


    I barely used this machine for the first couple years so the battery seems to be good.  Here is the System Profiler readout:


    Charge Information:

      Charge remaining (mAh):    5003

      Fully charged:    No

      Charging:    Yes

      Full charge capacity (mAh):    5089

      Health Information:

      Cycle count:    37

      Condition:    Good

      Battery Installed:    Yes

      Amperage (mA):    287

      Voltage (mV):    12579


    Anything here that looks like it might be bad?  I can't see anything wrong. I took it out and checked the cable but it also seems to be snug.  Or could it be too snug?


    Edit: OK, somehow this post was added on to the wrong thread...

    I had a problem with my MacBook Pro 13" (2012) when the keyboard and trackpad stopped working for seemingly no apparent reason. When I consulted with Apple Care, they had me reset the PRAM, which did the trick for me. From what I understand, the PRAM is memory that the computer uses to keep basic display and input preferences and info, even when the computer's turned off.


    Weeks ago I had installed a 3rd party mouse and keyboard. Even though I wasn't using them when the problem happened, Apple Care said maybe the software accidentally interfered.


    To reset the PRAM, I restarted the computer, and when the apple screen came up and the chime happened, I pushed COMMAND+OPTION+P+R (four keys), and waited for it to re-chime a couple times. Then the keyboard & trackpad worked again! See the About NVRAM & PRAM page for details.


    Might not be a cure-all, but it helped in my situation.
