Hi, I'm working on macOS support in Nixpkgs, sponsored by the Nix 🖤 macOS Open Collective. I'm a long-time macOS user and started using Nix almost 4 years ago.
This thread's intended to be a place for monthly status updates on what I've been working on and community feedback of painpoints macOS users experience.
I started tracking the state of macOS in issue #116341 Status of macOS. It's a convenient place to keep track of known issues. I try to keep it up to date on an overview level.
Nixpkgs currently uses macOS SDK version 10.12. This is fairly old and it is starting to generate issues where newer software can't be built for macOS because it relies on features in newer SDKs. The first goal is to get this updated. I've been working on bumping it to 10.13, the last version my local machine supports, as a way to familiarize myself with the process. This should make it easier to update to at least 10.14, the oldest version still supported by Apple, and likely newer versions using cloud resources. I've gotten the first three stages of the Darwin stdenv bootstrap to build (there's 4 bootstrap stages and 1 final stage).
