Gizchina News of the week
Mac OS X turned 20
Today, macOS, Apple’s proprietary operating system, is one of the top three market leaders. The current macOS Big Sur amazes with its beautiful interface design and wide functionalities. The history of this operating system began 20 years ago, on March 24, 2001, when Mac OS X 10.0 Cheetah was avilable, which stood out for the beautiful Aqua graphical interface.
Of course, Mac OS X Cheetah was far from Apple’s first operating system. Before it, the Californian company released a number of operating systems of the Mac OS family, with which, nevertheless, Cheetah had much less in common than with the current Big Sur. Mac OS X 10.0 laid the foundations for interacting with an Apple computer and brought in elements that are preserved in current versions of the Apple operating system.
Mac OS X Cheetah, although it amazed the imagination with its wide functionality and beautiful design, was still not without its drawbacks. The main drawback was just the interface. The fanciful graphical shell was very demanding on the hardware resources of the computer, which negatively affected the stability and performance of the system. It’s also worth noting that Cheetah was not free of charge. Its cost was $ 129. Apple’s operating systems became free only in 2013.
After Mac OS X Cheetah we saw the 10.1 Puma edition. This version of the operating system has significantly improved stability. As you can see, Apple began to call its OS by the names of big cats. This tradition continued until 2013, when versions of the operating system began to receive the names of tourist destinations in the state of California.
