I am trying to "burn" (yes I know thats not the right term) an iso for xubuntu onto my usb pendrive. I am on mac hardware but I have ubuntu installed and I would like to be able to do it without having to boot into mac os x. I have tried unetbootin and sudo dd if=xubuntu.iso of=/dev/sdb1
but none of them worked. Any help is greatly appreciated. Thanks
Additional info: I am on an intel mac, not one of those old powerpc things. It is a mid 2012 (I think) macbook pro
