 ### 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.

+
+## 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" ]; 
+```
