Macintosh HD Icon appeared in the display just like a thumb drive
MacBook Air 15-inch, M2, 2023
I can't remember the keystrokes to make the icon appear. I cannot find a mechanism to remove the icon. The answers on the support community imply there is a setting item in Finder. I have yet to find a settings item in Finder. I have not found a corresponding setting in the Setting menu.
