Yeah, So I get a "command not found" when I try and use airdrop, I even double checked to see if it was installed and it was.
I'm using the backtrack 4 vmware image.

Can anyone help? Thanks.

I haven't seen anyone take apart the screen with out destroying the glass. iFixit didn't take apart the screen because then they can't sell it.

YOU CAN NOT REPLACE THE CARDS! They are built into the screen half that you can not take apart., And it won't work in VMware anyways. The only new Macbook you can replace the card on is the Plastic...

The N cards use a different chip set then the G cards. They use Ralink RT2770 RT2750 chip sets, now I don't know if this is compatible or not, I haven't checked, but it is something to watch out for....

Put the key in again and it should fix it. I have this problem with win 7, VMWare and bootcamp.

I've got a copy on a CD somewhere around here. But it looks like you already solved your problem. :P
