Problems with booting Live USB on MacBook Pro

[SilentViper]

As a programmer and electronics engineering student I have a decent idea of what to try to fix this issue, thus I've followed http://docs.kali.org/installation/kali-linux-live-usb-install and that didn't do anything, it doesn't show up as an option when booting holding down the alt/option key. rEFIt doesn't help much either, although it does see the thumbdrive, it denotes it as a legacy os. When trying to boot from it in refit all i get are numerous errors like "device not found" (I'll reboot in a sec and get a pic of the output and reply the pic). I've also converted the iso to an img using
hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/kali.iso and that didn't change anything either. I even booted into my Win8 install and followed the live usb installation instructions for such, still no luck. and Yes, the thumbdrive does boot in my HP laptop, just not in my MacBookPro5,2

heres the output of diskutil list

/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: FDisk_partition_scheme *16.0 GB disk2
1: 0x17 2.2 GB disk2s1

i've used this usb for making a windows 8 install USB and also a OSX lion USB. I can't get my mac to recognize it when formatted as a live cd. I am aware that at one point Ubuntu had a separate mac disk because of some obscurity of the newer mac boot sequence i guess. Muts, if you see this, have you looked into such? Here's what i can find on the subject http://mirror.anl.gov/pub/ubuntu-iso/DVDs/ubuntu/12.04/release/
This image is adjusted to work properly on Mac systems.

Thank you in advance for any help / input

My ivy bridge Air booted it fine. Once. Stock i386 image.

Ever since that boot, it fails. Still works on normal PC's though.

I've managed to get a live USB working through http://forums.kali.org/showthread.php?271-How-to-EFI-install-Kali-Linux but now that i have a booting usb then when i try and install it repeatedly fails bootloader installation. And now im getting a (initramfs) prompt. other times i get a no suituable mode found, booting anyway error. :/ I've used the VM of Kali and loved it but im still fighting it to work on raw hardware.

34d30y, I'll give that a read and try that thanks, i'll try to let you know how it goes

At this point i do have a working live usb, although it takes booting individual commands, it does work. I managed to install and now i'm stuck at an initramfs prompt :/

@SilentViper If you don't mind me asking, how did you managed to get write access to create de EFI folder after flashing the usb thumb with that "how-to"?
