I seem to remember, maybe incorrectly, that if I wanted to determine Safe Boot Mode or not I could start at "About This Mac" menu. Am I wrong? All I get now are System Settings. I don't remember using an app to get there. Is this new?
It doesn't show up there under 10.3, 10.14 or 12.7. However, it does show up on the "splash screen" in versions that had such a thing. An example of the screen is attached, although in this image it doesn't have the Safe Boot text.
Maybe I just imagined this, but I used to go to About This Mac. There was a link to System Information (what is now System Settings), as now I must run the Application System Information. Its no big deal, just wondered why I was going through ASI in past.
