Perform a Safe Boot

Simply performing the Safe Boot may resolve this issue.

    Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
    Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).

    Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
    If your Mac starts up as expected, immediately try restarting.

If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
