Macintosh OS System 7.5.5 was installed on Apple Watch thanks to the ingenuity of a developer who managed to create a hack through which the operating system was tricked into running on the smart watch hardware created by the Apple company for users.
Macintosh OS System 7.5.5 was released 19 years ago by Apple and its installation on a smartwatch in 2015 seems hard to believe for many, but these small products have hardware at least as good as a computer two decades old.
The installation of Macintosh OS System 7.5.5 in the Apple Watch was possible thanks to watchOS 2.0, but also to the Mini vMac Macintosh Emulator, the emulator being the one that allowed the installation of an old operating system on a new device, offering compatibility with its hardware.
At the time of release, Macintosh OS System 7.5.5 was designed to run on a PowerPC Mac, those computers working with processors designed for desktops and not with chips found in smartphones launched 4 years ago.
To be honest, running Macintosh OS System 7.5.5 on the Apple Watch demonstrates how versatile Apple's products are and how much can be achieved by developers who are smart and brave enough to try things that seem impossible to many.
