Number pad on extended keyboard stopped working after updating to OSX 10.9.1. Testing keyboard on old system still works perfectly.
Expanded keyboard stopped working correctly after updating my system from OSX 10.8.6 to OSX 10.9.1 and now 10.9.2. The keypad numbers do not work although the numbers along the top of the keyboard work fine. Moving the keyboard back to computer still using 10.8.6 and it works fine.
