If your Mac no longer starts up successfully, these steps might help resolve the issue:

  1. Press and hold the power button on your Mac for at least 10 seconds, then release it. If your Mac is on, it turns off.

  2. Unplug all external devices from your Mac, including any displays and USB accessories, and remove any card inserted in the SDXC card slot. Then turn your Mac on.

  3. If the issue persists, reset the SMC as described for notebook computers with a non-removable battery.

  4. If none of these solutions work, please contact Apple Support for further assistance.
