Yeah I remember using BootCamp back then. FreeBSD also works quite well on the MacBook Air mid-2014, but without WiFi.

Edit: I didn’t bother to look into wifibox which is a FreeBSD package that runs a Linux VM for the WiFi driver, that could work. Also didn’t bother to check the webcam. However both WiFi and webcam work under various Linux distributions, but it’s typically a third-party Broadcom driver that has to be added outside of regular package repos.
