How to “burn” an iso to a usb thumb drive using a MAC...

So from time to time, it is necessary to put an iso onto a USB thumb drive… Back in the day, it was simple to just burn it to a blank disc but many servers and computers don’t come with DVD/cd drives anymore. I don’t see this as a bad thing, certainly, I almost never use the portable blue ray I purchased with my last computer…

Here is how to do it in the terminal, still the cleanest way…

First, run then insert your USB stick and run againdiskutil list
• diskutil list to see the disk node (e.g. /dev/disk2).
• Now run diskutil unmountDisk /dev/diskN
• and do sudo dd if=/path-to.iso of=/dev/rdiskN bs=1m
• When finished diskutil eject /dev/diskN
