Reinstall El Capitan or Later Without Erasing Drive


Please be sure you back up.


  1. Restart the computer. Immediately after the chime hold down the Command and R keys 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 icon in the toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Reinstall OS X and click on the Continue button.


Now try updating once again.
