Macintosh HD is grayed out. But the Mac seems to be running okay.

Season's Greetings!

Went to the Disk Utility app to see if the drive I had just plugged in mounted okay. It did. Then I noticed the grayed-out Macintosh HD line (see below). I don't recall ever seeing this before.

Yeah, I'm still on Monterey. I just might upgrade tomorrow. I'm looking forward to the new Context Menu function and its keyboard shortcut!

Should I try to mount it? Ignore it? Something else?

TIA!
