If you're only able to get to Windows, and if nothing is actually broken you can switch back to macOS normally in one of two ways:


  • Bring up the Boot Camp Support in your Windows system tray (near the clock) to see if you can select to startup with your Mac there.
  • Shut down the power and when you turn it back on hold down the OPTION key and see if your Macintosh HD shows up as an option.


Let me know if this is not the case.
