Q: My computer won't shut down or restart

There was a systems update and after I installed it my computer fails to shut down or restart. I have to hit the power button to get it to turn off. When I do shut down all it does is get rid of the tool bar and my desktop icon leaving me a just my desktop background. Now i have an update that requires a restart. What should I do?

    Outdated software for a Wacom tablet can prevent shutdown. If you no longer use the device, please remove the software. Otherwise, update it to the latest version from the manufacturer's website.

    After following the removal instructions linked above, you may also need to open the Users & Groups pane in System Preferences, select the Login Items tab, and delete any Wacom-related items. That's because the uninstaller is defective.

    Back up all data before making any changes.
