Repair guides, support, and troubleshooting information for the first 13-inch MacBook Air to feature Apple's ARM-based M1 SoC (with an 8-core CPU and up to an 8-core GPU). Released in November 2020 and identified by model numbers A2337 or EMC 3598.
I am a little confused by the Self-Service Repairs from Apple, and what is and isn't possible.
When I attach a second hand screen (genuine Apple) it gives me the option to finish the repair and it calibrates accordingly.
When I try a second hand Touch ID (genuine Apple) it fails to recognise it as being a genuine part.
My questions are - is it possible to calibrate a Touch ID now through Apple's program? And if so, would I need to buy a new button through the Self-Service Repair from Apple?
I was going through the self repair program information, and every indication is that the Repair Assistant seems to be able to recalibrate a Touch ID board, at least one purchased from Apple. They don't differentiate that repair from any other one they talk about, so I don't know if there is some restriction on only working on one you bought directly from Apple vs. a used part, but it does specifically mention repairing Touch ID on the M1 MacBook Air.
At this point we're really only guessing; only Apple can authoritatively answer the question of why you can't seem to calibrate a used Touch ID board since they show that process in operation. @flannelist Alisha, do you have any thoughts on this?
You are mixing different aspects of Apples Security
Parts Serialization - To kill off knock off parts (not a real issue) - Using the re-serialization (calibration tool) which only works with real Apple parts.
TouchID - Systems data security - The TouchID is married to the its mated logic board and no other!
I just tested this, because I found conflicting information. A Macbook Air M4 with Find My disabled. I installed a new logic board from selfservice and left the old TouchID in place. It doesn't work, it won't pair.
