A Hackintosh (/ˈhækɪntɒʃ/, a portmanteau of "Hack" and "Macintosh") is a computer that runs Apple's Macintosh operating system macOS on computer hardware not authorized for the purpose by Apple.^[1] This can also include running Macintosh software on hardware it is not originally authorized for. "Hackintoshing" began as a result of Apple's 2005 transition to Intel processors, away from PowerPC. Since 2005, many Mac computers have used the same x86-64 computer architecture as many other desktop PCs, laptops, and servers, meaning that in principle, the code making up macOS systems and software can be run on alternative platforms with minimal compatibility issues.^[2] Benefits cited for "Hackintoshing" can include cost (older, cheaper or commodity hardware), ease of repair and piecemeal upgrade, and freedom to use customized choices of components that are not available (or not available together) in the branded Apple products. macOS can also be run on several non-Apple virtualization platforms, although such systems are not usually described as Hackintoshes. Hackintosh laptops are sometimes referred to as "Hackbooks"
