Released on March 24, 2001, Mac OS X 10.0 Cheetah is the first major official release of the modern Mac operating system for Power PCs. It featured a completely redesigned user interface called Aqua and a new Unix-based architecture. Compared with classic Mac OS 9, it has a more modern design and introduced a few new built-in applications, including Mail, TextEdit, Sherlock, and PDF support.
Despite its age, you may still want to run Mac OS X 10.0 Cheetah due to nostalgia or technical research. If you have an original bootable CD of Mac OS X 10.0 Cheetah, use it to boot your PowerPC.
