If your Mac doesn't start up all the way

If your Mac doesn't start up all the way or needs you to do something during startup, it may stop at one of these screens.

Prohibitory symbol

A circle with a line or slash through it means that the selected startup disk contains a Mac operating system, but it's not a macOS that your Mac can use. You should reinstall macOS on that disk.
