As the only release engineer at $work, I have been tasked with creating the bootable USB devices of our FreeBSD-based product to send to the Contract Manufacturer. Every time a new release made it to General Availability (GA) status, Sabine would drop off a couple USB sticks and tell me which build to load onto them.
Wanting to empower her, I set out to create a better approach; one that did not involve dropping to the command-line and tapping-out a “dd” command. Meet a new AppleScript, named “WriteImage” written to take the guess-work out of the process.
With WriteImage you can now take the USB image file (*.img or *.img.gz) and drop it on the AppleScript droplet. It automates the process of generating the necessary commands to image the file onto hardware USB. Tell the app through a series of clicks or drag/drop actions which image to write, it then prompts you to insert a USB device, and then asks for confirmation (twice) before launching Terminal to do the dirty work.
Let’s see it in action (photo tour):
