    Reset the SMC.

     

    Read all the steps.


    Before Resetting the SMC

     

    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.

     

    1. Press Command + Option + Escape to force quit any application that is not responding.
    2. Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    3. Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    4. Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
