Ubuntu's Macbook Webcam Fix

Recently, I need to revive my old Macbook Pro 2015 13". I installed Ubuntu 22.04 LTS, but somehow the webcam doesn't work at all. Here is the steps that you need to fix it:

# clone facetimehd-firmware
git clone https://github.com/patjak/facetimehd-firmware.git

cd facetimehd-firmware

# compile and install
make
sudo make install
