Mac OS X 10.1 (code named Puma) is the second major release of macOS, Apple's desktop and server operating system. It superseded Mac OS X 10.0 and preceded Mac OS X Jaguar. Mac OS X 10.1 was released on September 25, 2001, as a free update for Mac OS X 10.0 users.
The operating system was handed out for free by Apple employees after Steve Jobs' keynote speech at the Seybold publishing conference in San Francisco. It was subsequently distributed to Mac users on October 25, 2001, at Apple Stores and other retail stores that carried Apple products.
Mac OS X 10.1 was codenamed "Puma" because the internal team thought it was "one fast cat."[2] In January 2002, Apple switched to using Mac OS X as the default OS on all new Macs at the time starting with the 10.1.2 release, replacing Mac OS 9.[3]
