Try these simple steps before contacting Apple for help.
If you experience difficulties with your Mac, try these troubleshooting
steps. If the issue persists, proceed to the next step. As a precaution, you
should back up your data before you perform any of these steps.
1. Check connections.
Turn off the computer and ensure that all cables are securely
connected to the computer. Turn the computer back on to see if the
issue is resolved.
2. Disconnect peripheral devices.
Turn off the computer. Disconnect all peripheral devices except the
display, mouse, and keyboard. Turn on the computer. If the issue is
resolved, try to isolate it to a particular peripheral device by turning
off the computer, reconnecting devices one at a time, and turning on
the computer after connecting each device.
