MagSafe problems on M2/M3 Airs are almost always the cable or port.

Yeah, the MagSafe connector on these MacBooks can be flaky, but nine times out of ten it’s something stupid you can fix in two minutes.

The most common issue is the LED on the connector either not lighting up at all or blinking amber when you plug it in. That usually means the connection isn’t clean. Pocket lint, dust, or a tiny bit of debris can get into the magnetic recess on the laptop or the connector itself. Grab a toothpick or a soft brush, clean both sides gently, and try again. That fixes most “not charging” complaints.

If cleaning doesn’t help, swap the cable if you have a spare, or try a different USB‑C charger (the Air can charge over USB‑C too). A surprising number of “bad MagSafe” cases are just a frayed cable or a faulty power brick. Also check that you’re using the right wattage — the M2/M3 Airs top out at 67
