When former Google employee Will Scott had the chance to visit the Pyongyang University of Science and Technology, he also purchased a copy of North Korea's "Red Star 3.0" operating system before returning to America.

Little was publicly known about the Red Star software at the time.

North Korea used to use Windows, but it has since created Red Star, which is designed to look a lot like Apple's Mac OS X operating system. As early as 2013, North Korean leader Kim Jong Un had been seen using an iMac, and a few years later, a MacBook Pro.
