Does the new 24" iMac Touch ID keyboard work with Mac's with the T2 Chip?
Solution 1:
The Touch ID feature on the new keyboards only works with the M1 chip.
Implemented wirelessly on Magic Keyboard, it uses a dedicated security component on the keyboard that communicates directly with Secure Enclave in M1, creating an encrypted channel to protect users’ fingerprint data from end to end.
