Mac OS X V10.1

Mac OS X V10.1

Mac OS X version 10.1, code named "Puma", is the second major release of Mac OS X, Apple's desktop and server operating system. It superseded Mac OS X v10.0 and preceded Mac OS X v10.2. Version 10.1 was released on 25 September 2001 as a 'free update' to version 10.0. The operating system was handed out for no charge by Apple employees after Steve Jobs' keynote speech at the Seybold publishing conference in San Francisco. It was subsequently distributed to Macintosh users on 25 October 2001 at Apple Stores and other retail stores that carried Apple products. The operating system was better received than Mac OS X version 10.0, although critics claimed that the operating system was still lacking features and was plagued with bugs.
