March 17, 1988: Apple sues Microsoft for allegedly stealing 189 different elements of its Macintosh operating system to create Windows 2.0. The incident, which causes a deep rift between Apple. Mac OS, operating system (OS) developed by the American computer company Apple Inc. The OS was introduced in 1984 to run the company’s Macintosh line of personal computers (PCs). The Macintosh heralded the era of graphical user interface (GUI) systems, and it inspired Microsoft Corporation to develop its own GUI, the Windows OS. System 7, codenamed 'Big Bang', and also known as Mac OS 7, is a graphical user interface-based operating system for Macintosh computers and is part of the classic Mac OS series of operating systems.

The version of Mac OS X 10.6.0 raised the optimization to Intel-based processors further, the new operating system is no longer available for PowerPC Macintosh or pure 32-bit intel processors. In return the user receives a pure 64-bit operating system optimized for performance on multiple processors. Mac OS 7.6 is a fine system, but given its close similarity to System 7.5.5 and the fact that it costs money, I can’t recommend paying for a copy unless you’ve got a Power Mac or need support for partitions larger than 4 GB. System 7.5.5 and Mac OS 7.6 are great system versions for vintage Macs that have what it takes to use.
