circle with a line thru it?
my Mac book pro doesn’t open- screen shows only a circle with a line thru it. Started out of the blue, did not respond to rebooting.

Hi Yenracbill,
Thank you for contacting Apple Support Communities. Based on what you stated, it seems like the MacBook Pro will not boot to the desktop. It sounds like you have a prohibitory symbol. I would recommend you read this article and use it to help troubleshoot the issue.
Take care.

Prohibitory symbol
When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from.
If you're using your Mac at a school or business, it might be trying to start from the wrong version of macOS. Contact your IT department for more help.
If this is your personal Mac, try reinstalling macOS using macOS recovery.

Take care.
