First,I have MBPR 2015 with Yosemite V.10.10.2 (14C2055).
Second,I made a USB Live Drive followed by offical website document.
When I use kali-linux-2.0-i386.iso as iso image in USB drive ,computer always launch OS X in boot list.
When I use kali-linux-2.0-amd64.iso as iso image in USB drive,computer get freeze in Kali USB live screen.
Is there something wrong with my steps? Thx
