Simple google search found the answer:

How to Boot Linux from USB on Macbook Pro [Archive] - Ubuntu Forums

Oddly enough, I also used a Kingston 2gb stick (works perfectly as I post this) and a Cruiser 8gb (no u3 on it as ive formatted, wiped, and iso booted it a few times, but for the life of me, I cant get the Cruiser to boot BT4.

I use UNetBooten, and it works fine on the kingston, a Lexar (both 2gb) but the Cruiser just won't do it. Any other thoughts on this? Something to do with the size of the drive perhaps?

Thanks for link, i finally created irefit on my mac and now it enable to boot in usb device. but if i choose the usb device(bt4) it keeps me giving error,something wrong with my usb installation.

@Galameth

Were on a same boat,i uses sandisk cruzer 8gb also.and up to know i couldn't fix my problem.

Its been 2 days and 2 nights for now, trying to figuring it out. i also try to install BT4 using my other PC with puppy linux 5.0.1 installed on it.

Any link step by step guide installing live usb bt4?

unetbootin didn't work for me. pc/linux.

Step by step? Try:
1) Boot from the live DVD.
2) Make a directory for your mount point => mkdir /mnt/sda1
3) Make a directory for your mount point => mkdir /mnt/cdrom
4) Stick in your USB flash drive (I use a 2 GB Kingston for my USB).
5) Mount your USB => mount /dev/sda1 /mnt/sda1
6) Partition your USB => fdisk /dev/sda1 (just use one large partition)
7) Format your USB => mkfs.ext3 /dev/sda1
8) Mount your DVD => mount /dev/hdc /mnt/cdrom (it may already be mounted in /media).
9) Copy all the contents from the DVD to the USB drive => cp -vr /mnt/cdrom /mnt/sda1
10) Navigate to /mnt/sda1
11) Run GRUB => grub-install --recheck --no-floppy --root-directory=/mnt/sda1 /dev/sda1
12) Navigate to /mnt/sda1/boot/grub and run => cat menu.lst
13) Check the menu to see if has the correct pointers (it ususally will).
14) Run nano on the menu to correct the screens => nano menu.lst
15) Add vga=0x317 at the end of the kernel line for the 1024x768 listing.
Add vga=0x314 at the end of the kernel line for the 800x600 listing.

The particulars listed may not be idiot proof - I'm assuming that you have some slight knowledge of linux and will understand the commands and what extra to do. This is what I do, and I have two USB disks that I update like this all the time.
