1. Download the VirtualBox image for Kali 2.0
2. Import it into VirtualBox
3. Set up the machine as normal
4. In the network tab disable the network interfaces
5. Change to the Ports tab
6. Change to the USB portion of the Ports tab
7. Add a filter
8. Name it something, like Alpha
9. Open System Report on Mac, select USB on the left, then the wifi adapter
10. Fill in the Vendor ID and Product ID from System Report on the filter settings in VirtualBox (mine were "148f" for vendor and "3070" for product)
13. Dont' worry about any of the other fields 
14. Click "OK" to save, and that's it

It seems to have stopped working. Can't figure out what's up. Doesn't show any wireless networks all of a sudden.

Some output:
