A new hack has managed to load Chromium OS on to the previous-generation MacBook Air. The trick involves 'burning' an image of the OS to a USB flash drive and running Terminal prompts to move the OS and give it permission to run as a boot drive on the Apple notebook. Because it needs to run on the Mac's solid-state drive for the firmware to recognize the boot process, it has to wipe out the Mac OS X install; the creator, Hexxeh, urges every user to backup any data.
