The team behind the super affordable Raspberry Pi computer platform has been working on their own desktop environment called PIXEL, and now it’s available for the Mac. PIXEL is built on Debian, so it’s a fully bootable system, and includes everything you need to be productive, the Chromium web browser, and more. They designed it so you can pop it on a USB flash drive or DVD and run it from there. PIXEL is still in an experimental stage, so don’t rely on it as your primary OS. It’s a free download at the Raspberry Pi website.
