How can you visibly tell the difference between MacBook Air Retina scr

Well. That’s a great question.

To be honest, this might be a bit tricky. The first thing I would check is if you can locate a different board number on the TCON board. I was hoping I had photos of my spare M1 TCON board on my phone to at least give you info for that, but I apparently do not. Those board numbers also may be identical, or may be the same across some models. But it’s the first thing that came to mind.

UPDATE: Now that I'm home, I dug out the board for the M1 machine. I am finding this may not be the best solution since the board number is actually underneath the sticker for one of the flex cables. However. I can confirm that the board number for the M1 (A2337) is 820-01891-02. Also don't worry, this board was already toast. It came out of a friend's machine whose (ex)boyfriend went "Bender Bending Rodriguez" on it and tore the whole display off the rest of the chassis.

I don't think I have the juice to rip my 2019 A1932 apart tonight for science, but maybe tomorrow. I actually use that so I would be a bit sad if it came to harm.
