how do I find the last location of a divice I can't find and think was stolen

Hi,

You can't find last location of lost your MacBook Pro, though you could find the latest place when a thief power up and connect to WiFi with find your Mac.

If your Mac is lost or stolen - Apple Support

You should call police and tell them about the circumstance you face with now, also.

Open “find my” app, hopefully you have had location turned on that device? Then click device icon, and ser if its listed, then click. Try icloud if not there.
