IDG Contributor Network: Why and how to run Linux in macOS ... for free

MacBooks are quite popular within the commercial open source community. I cover a lot of open source events and all I see are MacBooks running macOS. I myself carry a MacBook to such events.Why?The short answer is that it just works.The longer answer is that macOS is UNIX so you get access to all utilities, commands and tools that you get on your desktop Linux box, including running cronjobs, rsyncing files and writing USBs with the ‘dd’ command from macOS's native Terminal app.
