What might cause mouse and keyboard freezes after updating to OSX 10.8.2?

After the 10.8.2 update, keyboard and mouse input is hanging intermittently on my 2011 MacBook Air. It occurs in several applications (have tested with Safari and App Store). The keyboard input and mouse just stops working for a few seconds, then some of the typed text is input at the cursor.

Does anyone know a solution to this or tip to help me find one?

Console log shows a lot of these

2012-09-22 15:22:16,000 kernel[0]: AppleUSBMultitouchDriver::_deviceGetReport - DeviceRequest for reportID 0x0 returned with result 0xe000404f - retrying

Solution 1:

Several users have found this to work (and as far as I can evaluate, it fixed it for me as well):

  • Log in/switch to an administrator account
  • open Terminal
  • sudo rm /Library/LaunchAgents/com.google.keystone.agent.plist
  • sudo rm /Library/LaunchDaemons/com.google.keystone.daemon.plist

Solution 2:

For me it was (a super old) version of carbon copy cloners plist:

sudo rm /Library/LaunchDaemons/com.bombich.ccc.plist

removing it brought instant joy (yay!)
