Monterey (macOS 12.0 or 12.0.1 in fact) is now available since October, 2021.
I compare this version to the previous one in Big Sur I presented in macOS Big Sur and smart cards status.

idea what that means. Except that Apple made changes to the code.
I have not yet made many tests of the PC/SC layer. So far it works fine.
Crypto Token KitCryptoTokenKit is the native smart card API since the complete rewrite in macOS Yosemite 10.10 (OS X Yosemite BETA and smart cards status).
The framework directory changed again. There is no more a
But you can of course still use the CryptoTokenKit framework. My Objective-C sample "PC/SC" sample in Objective-C (synchronous) still builds and works fine.
