|Version of Mac OS X|
|Architecture||PPC, i386[note 1]|
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 but not on Mac OS X 10.0 (Cheetah), and it fixed several stability issues; though it was still met with a mixed reception. 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).
