Hello, new here.
I haven’t installed yet. Have been reading first. Looking to build a custom ISO to include firmware and drivers for MacBook Pro 15,1. I have the-non free firmware from my Macbook, also have files from T2 Linux.
I’ve read about adding broadcom\_sta but I know this doesn’t work for my laptop. I’d like info on how I create the nix packages to include my firmware. Where do I put the files? how to create a nix package?
There is probably some thread here but I haven’t found it. Any help would be very much appreciated.

The NixOS Wiki links here: [https://github.com/tpwrules/nixos-apple-silicon/blob/6e324ab06cb27a19409ebc1dc2664bf1e585490a/docs/uefi-standalone.md](https://github.com/tpwrules/nixos-apple-silicon/blob/6e324ab06cb27a19409ebc1dc2664bf1e585490a/docs/uefi-standalone.md)
It contains instructions for creating a custom ISO, etc. It does look to be a fair tad more steps than a normal NixOS install, just a warning this is definitely not exactly the easiest path for a new user of NixOS. Of course, please don’t let that discourage you!
