我已经在这个网站https://medium.com/@racter/how-to-install-ubuntu-16-04-on-a-retina-macbook-11-2-74e7779c0e47上尝试了解决方案：
$ cd /etc/local/src
$ git clone https://github.com/patjak/bcwc_pcie.git
$ cd bcwc_pcie/firmware
$ sudo make
$ sudo make install
$ cd ..
$ sudo make
$ sudo install
$ sudo depmod
$ sudo modprobe -r bdc_pci
$ sudo modprobe facetimehd
但是，我在第一个sudo make后收到以下错误。
Checking dependencies for driver download...
