MacBook Pro won’t restart

When I updated to Sierra, my MacBook Pro wouldn’t restart until I quit installer. I quit it and now it won’t restart. Just “bong” and black screen.

MacBook Pro 15″, macOS 10.13

Try this:


Reinstall El Capitan or Later Without Erasing Drive


Please be sure you back up, if possible.


  1. Restart the computer. Immediately, at or before the chime, hold down the Command and R keys until the Apple logo and progress bar appear. Wait until the Utility Menu appears.
  2. Select Disk Utility and click on the Continue button.
  3. Select the indented (usually, Macintosh HD) volume entry from the side list.
  4. Click on the First Aid button in Disk Utility's toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Install OS X and click on the Continue button.
