You can consult the [wiki](https://wiki.t2linux.org/) 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`](https://github.com/Redecorating/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.EFI` file to `bootx64_original.efi`.
- Installs the `apple-set-os-loader` hook in its place as `bootx64.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:
1. Add this into your `configuration.nix`:
```
hardware.apple-t2.enableAppleSetOsLoader = true;
```
2. **Rebuild your system**:
```
sudo nixos-rebuild switch
```
