    My keyboard and mouse stopped responding.  A USB keyboard and a USB mouse worked fine. 


    I rebooted my computer, replaced the keyboard batteries, and even ran the script to see if there were any items I should kill.  I didn't see anything suspicious, then on a hunch checked the Bluetooth status (System Preferences>Bluetooth) and found it was deselected.  Never happened before and I suspect it was related to using my cell phone.  After reselecting Bluetooth, everything worked fine.

    I know this may seem like a dumb question but when I ran the script in terminal it produced the following:

    unknown0021e9e32258:~ kevin$ kextstat -kl | awk ' !/apple/ { print $6 } '






    unknown0021e9e32258:~ kevin$


    Now that I have this information, how do I go about deleting these files to hopefully solve my issue.


    My issue is very similar to everyone elses here, after leaving my keyboard and trackpad stationary for a minute of two, it becomes nonresponsive. If I then close the lid and let the mac go into sleep mode for just a second and reopen the lid it begins to work again. This has been a very consistent fix the an annoying problem. The apple ppl say that its a harddrive issue but I beg to differ. Please let me know how I can go about deleting these files.


    Thanks in advance.

    None of this worked for me. It turned out to be a hardware issue - the MacBook wasn't able to detect the keyboard due to a copper wire under the battery sticking out. Take out the battery and push the copper strip down. Here's a more detailed explanation with a picture:

    If it's a white macbook it probably is not a software problem. The battery is probably swollen (which is a common problem with these models apparently) and putting pressure on the keyboard and trackpad causing them not to work. I had this same problem on my 2008 white macbook. For me it started where the mouse cursor would go haywire and I could click by gently touching anywhere on the bottom part of the laptop.


    I would highly recomend getting a new battery, which is what I will be doing when I get enough dough. I am currently using a usb keyboard and mouse.

    Hi, The keyboard for my imac suddenly not working for four keys - 7, J, U, M. I unplugged the UBS and plugged into another UBS connector, it worked.  But it didn't  take too long before the same problem happened again. Now I plugged the keyboard to a macbook. It has the same problem. Does it mean the keyboard has to be replaced? It used only one year. Is there anyway to fix it?

    Thank you.

    This solved my problem. Thanks!

    Had accidentally pressed the option key too many times. If this happens to you, also make sure to turn off the keyboard shortcut (5 times option key).

    This can be done in Preferences under    Accessibility > Options  . Here turn off the 'press the option key five times to toggle Mouse Keys' setting.

    It's looking like my MBP Retina is going to get a visit to the apple monkeys at the store, because even after reinstalling the OS I'm still having this problem. It's a major productivity limiter, since I can't use the machine without its keyboard working, and constantly rebooting the machine isn't acceptable, particularly when it might work again for 3 days or for 10 minutes before the keyboard stops working (again).


    So much for "it just works" I suppose.


    This is the worst experience I have ever had with a computer in over 20 years, so I think this piece of junk is going to be my last mac ever. The machines are just not reliable, and apple's customer service is crap.

    I have a OS X too. My keys didn't work, but now it works!


    What I Did:

    1, Click on System Preferences.

    2, Click on Accessibility. (It should be on the 4th row)

    3, Click on Mouse & Trackpad.

    4, If your "Enable Mouse Keys" is ticked, then tick it off.

    5, Hope it goes well!
