I just installed Ubuntu on my MacBook Pro Retina, but am having trouble getting the wifi working. I followed the steps posted at Ubuntu can't detect wifi networks on macbookpro 13.3 but when I run sudo modprobe wl I get the error modprobe: FATAL: Module wl not found
I don't have an ethernet adapter for this machine, so I'm not really sure what other options I have for getting network access on this machine on ubuntu.
