Problem kali on mac live usb

[Kali12345678]

Hi everyone, i have got a macbookpro 13" 2012 I think and a 32gb usb 3.0 formatted with disk utility fat32 where i have uploaded the ISO of kali 2016.1 64bit with Mac Linux USB Loader. I have installed refind boot loader for booting EFI. I tried for more then 12 hours everything, but nothing seen to work. When i start to boot kali then i Get a error:

Mount:mounting /dev/sda2 on /live/medium failed: invalid argument.

I tryed also to put the image in the usb pen from terminal with dd but i had the same problem there too. The partition is MBR, i tryed also GUID but i had only problem. Maybe i need to use an older version of kali but i don't want to use an older one. I tryed to use Burn the image on the USB pen like a Debian OS because i know that kali is based on Debian but nothing..

Thanks for helping
