Please see the below link and follow.

If your Mac starts up to a question mark.


  1. Make sure you have followed step 3. (While in macOS Recovery, use Disk Utility to repair your startup disk.)
  2. If you still have issue I suggest you to perform a Apple Diagnostics Test. https://support.apple.com/en-gb/HT202731 (Helps to know if any hardware issues)


Still if your issue is not resolved please contact Apple Support.
