just to reiterate, i had encouraging results with
it lets you create a boot stick, that's able to boot iso images.

didn't try it with Macs so far, but i'd reckon it'd work just as well ..ede

I then proceeded to use the Linux 'dd' command to copy the iso file to the first partition, which resulted in the partition format to switch to "ISO9660". The resulting flash drive is still not detected on a variety of Macs

Given that we are beyond the days of DVDs, might we perhaps return to one of the heavyweights (Ubuntu, Fedora, Debian)?
