Greetings Nosnuz,

Thank you for using Apple Support Communities. It seems like you upgraded your Mac mini and now you see a prohibitory symbol when you boot the computer. I would recommend you read this article and use it to help troubleshoot the issue.


Prohibitory symbol

User uploaded file

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.

About the screens you see when your Mac starts up


Take care.
