Bootable USB on Intel Macbook Pro??

[maltai]

Hi,

I was hoping to create and use a bootable USB drive install of Backtrack 4. Unetbootin does not have an OSX version. Has anyone else tried this before? I attempted to use the diskutil in OSX, but this did not work.

I've tried this with both backtrack 4 and windows xp through vbox. The os I installed by unetbootin was installed on the flash drive but would not boot. I installed refit on mac os to be able to select it at boot, but when it comes up, I select it and the screen goes blank.
