## NixOS Installers for T2 Macs

This flake can be used to build a NixOS installer that can be used with T2 Macs.

Prebuilt installers are available in the [releases page](https://github.com/kekrby/nixos-t2-iso/releases).

This repo provides two isos:
* `t2-iso-minimal`
* `t2-iso-gnome`

It is recommended to use `t2-iso-minimal` for installing NixOS. `t2-iso-gnome` can be used to preview what the system will look like after the installation.

## Building

You can build with this command:
```
nix build .#t2-iso-minimal
```

You need to have `nix` installed on a **Linux** host. If you are on macOS, you can use `podman` or `docker` with the `nixos/nix` image.

As iso files can be quite large depending on their content, they are split into multiple parts. You can join them with this command after downloading all the files for the variant you want:
```
cat t2-iso-<variant>.iso-part-* > t2-iso-<variant>.iso
```
