Double-check Connections

If HDMI not showing up on TV Mac, there may be an issue with your connection. Make sure your HDMI is connected and secure with your Mac.

  1. Turn off the device your HDMI is connected to and keep it connected to your Mac.
  2. Disconnect the HDMI cable from your Mac.
  3. Wait a few seconds, then plug it back into your Mac.
  4. Turn the HDMI device on.

HDMI Cable Connect

If it still doesn’t work, maybe your HDMI cable isn’t compatible or is damaged. Apple products tend to work the best with other Apple Certified cables, so your best bet would be to buy an Apple HDMI cable.

Detect Display Option

Alternatively, there is another solution you could try if your HDMI cable not working Mac continues to have issues:

  1. Go to System Preferences on your Mac.
