Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

I've been using llama.cpp on Mac Silicon for months now, and my brother, Chimezie has been nudging me to give MLX a go. I finally set aside time today to get started, with an eventual goal of adding support for MLX model loading & usage in OgbujiPT. I've been warned it's rough around the edges, but it's been stimulating to play with. I thought I'd capture some of my notes, including some pitfalls I ran into, which might help anyone else trying to get into MLX in its current state.

As a quick bit of background I'll mention that MLX is very interesting because honestly, Apple has the most coherently engineered consumer and small-business-level hardware for AI workloads, with Apple Silicon and its unified memory. The news lately is all about Apple's AI fumbles, but I suspect their clever plan is to empower a community of developers to take the arrows in their back and build things out for them. The MLX
