Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

I wanted to try the Chromium OS builds from http://chromeos.hexxeh.net/, but failed to create a bootable USB drive.

I followed the steps on the site:

  1. Download the Mac builder
  2. Download the vanilla .iso
  3. Run the builder (and tell it to use the .iso)

But when I tried to reboot and hold down the option key, the USB drive didn't show up.

When I rebooted back into OS X, it complained that the USB drive wasn't recognized. In disk utility it showed several partitions.

Has anyone had experience with Chrome OS on a MacBook?

The question as asked is rather broad (and answers probably won't help to solve your problems). You will get better results by asking a more specific question (which based on the current version of the question most probably is either "how do I get my USB drive back" or "how do I get Chromium OS work"). Feel free to ask separate (new) questions if you want to have answers for both topics. –  patrix Feb 14 '13 at 14:21

From my experience you are best downloading VirtualBox and launching it as a full-screen virtual appliance. Apple's EFI doesn't like to load USB drives that aren't OS X or Windows 7 installers. I have run into this same issue trying to run Ubuntu and Haiku from USB. If you have an optical drive you are better off burning the ISO to DVD and booting that way. You could also checkout rEFIt at your own risk as an alternate boot loader.

By the way it is normal for OS X to not recognize the format of the USB you created. That is because it is probably not in HFS+, NTFS or FAT. Not that it makes it any easier to boot.
