A friend handed me an old unwanted Macbook Pro and said "Have fun with it", so I decided to run it with Ubuntu. Before doing an actual installation, I tried it with a non-persistent USB stick. Everything worked fine except for wi-fi, which doesn't even show up in settings. The computer works fine with a wired connection to the router. When I start the computer with the Mac OS, wi-fi works fine.
Is there any reason to believe that the situation would be different if I did a full installation of Ubuntu?
