The wireless driver installed ok (i uninstalled the other one first, that was a bit weird but finished up ok), however when i ran it from the applications it just bounced on the dock and nothing showed up... rather strange. i searched using airport and no access points came up.
Regarding changing the other boot.plist file, how can i Access the /Extra directory? Lol I cant find it :P I fail haha.

Also,
Can i set the ctrl key to work as the cmd key?
Why, when i ran an uninstall command and it asked me for the root password, did it say it was incorrect, even after i made sure that it was the right password? i was then able to uninstall the thing by repeatedly clicking ctrl-c (to dismiss). I enabled the root account and then tried it with 2 passwords, it always said it was incorrect.
