Demonstration of MacOS Rhapsody DR 2 running on PC.
Audio Track used is Hungarian Rhapsody no 2, by List 😁

What is Rhapsody?
With MacOS 8.x/9.x Apple reached the limits to the capabilities classic MacOS and for Apple to move up in the fast paced world of IT it needed to modernize the OS significantly.
They chose to adopt a Unix based OS called NeXTStep (Steve Jobs again) and curiously enough it ran on Intel CPUs (!!!) – this video shows one of the developer releases of Rhapsody running on Intel Pentium II – the interface is quite similar to classic MacOS but underneath it’s radically different.

OS X would later be based off a XNU Kernel and the Darwin Open Source Operating system. Of course all the Apple specific libraries, including the “Aqua” GUI are NOT open source. OS X ran on PowerPC CPUs initially. But with the introduction of Intel based Macs OS X (Tiger) would be able to run both PowerPC and Intel applications with help of Rosetta and it returned to it’s old Rhapsody Intel roots.

With the Introduction of the M1 Macs Apple has done another major CPU platform shift and again uses Rosetta 2 technology to run Intel binaries on the ARM based M1 CPU.

Thanks for watching, Mark
