Isit possible to create a Live Kali USB that boots off windows AND mac, I have already setup a kali live usb that runs perfectly on windows.
I was wondering if there is any way i can add a few conf. files that allow it to boot off a mac also....or would that mess with the windows boot in turn?

Also, If i partition my usb to allow for persistence...if i log in through persistence, and upgrade and update, will this be saved onto the usb?
Or will it be discarded, and I'll need to update, upgrade after every login..??

Thanks so much guys
