Mac OS X 10.0 Cheetah

Mac OS X 10.0, dubbed “Cheetah” went on sale for $129 on March 24, 2001. It brought the Aqua user interface and technology like preemptive multitasking and protected memory to a wider audience than the Public Beta.

Cheetah required 128 MB of RAM, which seems meager today, but was more than most Mac users had in their systems at the time. Even machines that surpassed the system requirements ran slowly under Mac OS X, which was the number one complaint of users about the release.
