My late 2010 Macbookpro cannot handle the newest OS-X (yosemite) anymore. So here we go Ubuntu. The installation is quite smooth until the WIFI part.
This is for Ubuntu 14.04. The Macbookpro has Broadcom bc43xx chipsets.
First you need to install/remove some packages for the driver:
sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer b43-fwcutter
Then you need to UN-block the bcm43xx driver:
# blacklist bcm43xx
You will get some error messages, ignore them.
Finally, do this so when you restart your computer, WIFI is still there. Following this page:
echo b43 >> /etc/modules
