A programmer who was lucky enough to have access to Apple’s WatchOS 2.0 beta has used it’s native app capabilities to do something a little out of the ordinary. The programmer’s name is Nick Lee and he was able to port Mac OS 7.5.5 to his Apple Watch. In case you do not remember this version of Mac OS it is twenty years old and hardly of much use anymore especially on the watch’s small screen.
The feat was pulled of with the help of a recompiled version of Mini VMac, a Mac emulator that Lee recompiled for use inside of the WatchOS. The watch’s hardware is actually faster than what the OS originally debuted on and has more resources such as RAM as well. Mac OS 7.5.x shipped on systems containing 100Mhz precessors with just 24MB of RAM. The Apple Watch uses a processor called the S1 which is closely equivalent to the iPhone 4S processor known as the A5.
Although load times are reportedly slow it’s undeniably pretty cool to see an operating system that once took a large desktop computer to operate hang out on your wrist with room to spare.
