Help with Macbook and 12.10

view story

http://askubuntu.com – What is the latest version of Ubuntu I can run with working Wifi on my Macbook 4,1(early 2008)? I dual booted my Mac OSX Lion alongside 12.10 but can't figure how to get the wireless to work. Ergo, I downgraded to 10.10 for now. Is 10.10 the latest version I can have on my Macbook with working Wifi, or is there another? Am i simply missing a terminal code to fix the drivers? (HowTos)
