* Adds a deprecation warning to hardware.apple-t2.enableTinyDfr as it has been upstreamed to nixpkgs already. The package and option can be removed at the next release cycle to hopefully not break people's setup. * Adds an assertion to conflict hardware.apple-t2.enableTinyDfr with hardware.apple.touchBar. Having both enabled causes both tiny-dfr to fight for the same display device.
NixOS on T2 Macs
This is the nixos-hardware module of the T2 Linux Project.
Overall, most features (WiFi, bluetooth, audio, touchbar, ...) of Macs are supported, see this page for a detailed list of things that work and things that don't/partially work.
Following this guide is the recommended way to install, as it incudes the extra things you have to do on a T2 Mac.
You can consult the wiki for information specific to T2 Macs.
Unlocking Internal iGPU
The apple-set-os-loader-installer module serves as an installer for the apple-set-os-loader. This tool is designed to unlock the internal integrated GPU (iGPU) on certain MacBooks. See https://wiki.t2linux.org/guides/hybrid-graphics/ for more details.
What it Does:
Upon activation, this module performs the following:
- Renames the existing
BOOTX64.EFIfile tobootx64_original.efi. - Installs the
apple-set-os-loaderhook in its place asbootx64.efi. - Before the system boots the hook unlocks the iGPU and subsequently calls the original
bootx64_original.efi. - Enables the iGPU by default.
How to Implement:
- Add this into your
configuration.nix:
hardware.apple-t2.enableAppleSetOsLoader = true;
- Rebuild your system:
sudo nixos-rebuild switch
Note
: Always ensure compatibility and make backups of your data before making any system changes.
