I just recently installed ubuntu on my macbook and am trying to get the wifi to work. I have followed this thread https://help.ubuntu.com/community/MacBookPro9-2/Quantal but with no success. My outcome is a little different, here is a screenshot:
the first commands I enter do not result as suggested as well as the "b43-fwcutter command not found" where I stopped.
Not sure what other info to give, I would love to get this sorted out. Thanks.
