Hello and salute to all

I have been searching for months on the dual boot install of kali 1.1.0 and mac OS X yosemite, I have found only old ways that do not work. Is there anyone out there that has the answer? I have a late 2013 macbook pro retina with only 2 usb ports, I have access to no ethernet but only wifi. I do have a couple alfa cards in N series.

Thanks and any support or direction would help tremendously.

Cheers
