Symptoms

The trackpad on your MacBook Pro (Retina, Mid 2012) may become unresponsive after applying the MacBook Pro (Retina) Trackpad Update. This can occur when the update is interrupted by the computer going to sleep.

Resolution

If you have access to an external mouse or other pointing device, connect it and reapply the update. Do not disconnect the power or allow the computer to sleep during the update process.

Follow these steps if you do not have access to an external mouse or other pointing device:

  1. Press Control-Fn-F7 (this enables all commands via the keyboard).
  2. If the Updater application is on the screen, go to step 7. If the Updater application is not on the screen, continue to step 3.
  3. Press Command-Tab to go to the Finder.
  4. Press Command-Shift-U to open the the Utilities folder.
  5. Use the arrow keys to navigate to "MacBook Pro Trackpad Update" so it is highlighted.
  6. Press Command-O to start the application.
  7. The word "Update" should be highlighted in blue. If it is not, press the Tab key to highlight it.
  8. Press the space bar to initiate the update.
  9. Press Return to confirm OK.
  10. Enter your administrator password, then press return.
  11. Allow the update to finish. Do not unplug the computer, let it sleep, or interrupt the update while it is in progress.
  12. The word "Updated" with a green checkmark appears in the progress box when the update is complete. The trackpad should now be functional.
