i have a mac pro thirteen inch and today my number keys plus my left hand side shift keys just stopped working. i tried restarting the computer but that only led to me being locked out of my lap top in the restart window because i couldn't type in any numbers to enter my password. i am now only able to sign in under guest mode. any suggestions or help would be greatly appreciated as i am at my wits end over here.

MacBook Pro, Mac OS X (10.7.5)

    Hey cadmac,



    Thanks for the question, and welcome to Apple Support Communities.


    The following article provides isolation steps for the symptoms you mentioned:


    Troubleshooting wireless mouse and keyboard issues



    Use the Keyboard Viewer to test whether the keyboard keys are responding correctly when they are pressed.


    1. Choose System Preferences from the Apple () menu, then choose Language & Text from the View menu (or International from the View menu in Mac OS X v10.5 or earlier).


    2. Select Input Sources.


    3. Select the Keyboard & Character Viewer checkbox.


    4. Enable the input source for the keyboard layout you are testing by selecting the checkbox next to it.


    5. Make sure that "Show Input menu in menu bar" is enabled.




    6. Choose Show Keyboard Viewer from the Input menu in the menu bar, as shown.




    7. The Keyboard Viewer shows the keyboard layout.




    8. Type the key on the keyboard that doesn’t respond and observe whether the corresponding key highlights on the Keyboard Viewer. If it does, that particular key is functioning correctly. In the sample shown above the shift and command keys are being pressed.


    9. If the mouse keys feature in the Universal Access System Preferences pane is enabled, many of the keyboard keys may not respond as expected.


    10. Try starting up into single user mode to determine whether a software issue is causing the issue.

    This was very useful in helping me help my husband resolve his number key/shift character dilemma.  He uses two keyboards and he had the alternate selected.  Easy troubleshooting tips.  I'm normally not a MAC person but can usually  navigate through troubleshooting directions.
