Mac OS X Puma

Mac OS X Puma (10.1) is a version of Mac OS X that was released on 25 September 2001. It was more successful than its predecessor, because of the inclusion of features that existed on Mac OS 9.x but not on Mac OS X 10.0 (Cheetah), and it fixed several stability issues. Most builds of Puma were compiled for PPC (for public use) and x86 (for testing purposes for the upcoming Intel x Apple partnership, which would continue until the announcement in 2005).
