This article may have something about that here:


• If your Mac starts up to a circle with a line through it - Apple Support

//support.apple.com/en-us/HT210901


"A circle with a line through it means that your startup disk contains a

Mac operating system, but it's not a macOS that your Mac can use." 


[from this page If your Mac doesn't start up all the way - Apple Support]

"Learn what to do if your Mac starts up to a circle with a line through it (prohibitory symbol)."


  1. Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
  2. Use Disk Utility to repair your startup disk
  3. If Disk Utility found no errors or repaired all errors, reinstall macOS.
  4. If you still need help, please contact Apple Support.
