How to find a lost MacBook

Your tag line says that you have a 13" MacBook Air running macOS 15.7 (Sequoia). All MacBook Airs recent enough to run Sequoia have either Apple Silicon processors, or Apple T2 Security chips – which means that they all support Find My, if you enabled it.

However, the Mac needs to be powered on, with an Internet connection, in order to report a guess as to its location.

If your Mac is lost or stolen - Apple Support

Note that if you believe that your Mac has been stolen, and you do see a location, it would be unwise to go there to confront criminals in person. The Mac's guess as to its location is likely to be a lot less precise than an iPhone's, as the Mac does not have a GPS receiver chip. So you might go to the wrong place … and if you went to the right one, the criminals might cause you to lose more than just a computer.

You have two options.

1. Locate a device in Find My on iPhone - Apple Support
2. Retrace your steps and look for it the old fashioned way.
