### For wifi driver
broadcomt_sta was the best working driver I could find, however on the normal kernel, you need to `sudo modprobe -r wl` and `sudo modprobe wl`, however it was fully working on the zen kernel.
# MacBook Air 7,2
## Issues
> Wifi Driver doesn't work
### Solution
* generated NixOS-Configuration via nixos-generate config on MacBook to load following modules:
```nix
boot.kernelModules = [ "kvm-intel" "wl" ];
boot.extraModulePackages = [ config.boot.kernelPackages.broadcom_sta ];
```
> Camera doesn't work
### Solution
```nix
hardware.facetimehd.enable = true;
```
* when added this line of code, another driver was loaded for the network controller, so wifi stopped working.
* by adding the modules to boot.initrd. both wifi and camera was working:
### Solution
```nix
boot.initrd.kernelModules = [ "kvm-intel" "wl" ];
```
