Well my technology life started with a really old Apple macintosh classic 2. If that means anything.
Just jesting Thomas - the original Mac operating system from 1984 has LONG disappeared - some discussion quoted below; modern Mac OS started in 2001-2 first described as Mac OS X, then OS X, and now macOS - all based on an underlying robust Unix system - likely the most reliable and safest major OS now available, but just my opinion (and likely that of others) - Dave
The current Mac operating system is macOS, originally named "Mac OS X" until 2012 and then "OS X" until 2016.[3]Developed between 1997 and 2001 after Apple's purchase of NeXT, Mac OS X brought an entirely new architecture based on NeXTSTEP, a Unix system, that eliminated many of the technical challenges that faced the classic Mac OS. The current macOS is preinstalled with every Mac and is updated annually. It is the basis of Apple's current system software for its other devices, iOS, watchOS, and tvOS. (Source)
