MITS realized that BASIC was a competitive advantage and bundled the software with computer hardware sales. Customers who purchased the computer, memory, and I/O boards from MITS could get BASIC for $75; the standalone price was $500. Many hobbyists purchased their hardware from a third-party and "borrowed" a copy of Altair BASIC.
A Hackintosh (/ ˈ h æ k ɪ n t ɒ ʃ /, a portmanteau of "Hack" and "Macintosh") is a computer that runs Apple's operating system macOS on computer hardware that is not authorized for the purpose by Apple.
