Mac OS X 10.1


Mac OS X 10.1 is the second major release of Mac OS X, Apple's desktop and server operating system. It superseded Mac OS X 10.0 and preceded Mac OS X 10.2. Version 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 no charge 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. The operating system was better received than Mac OS X 10.0, although critics claimed that the operating system was still lacking some features and was plagued with bugs.

Apple introduced many features that were missing from the previous version, as well as improving overall system performance.
This system release brought some major new features to the Mac OS X platform:
Although version 10.1 was a more efficient operating system than its predecessor, it still received its share of criticism.
Critics claimed that Mac OS X was still not fully developed in terms of reliability or functionality, and as such could not be used as a main operating system under normal conditions. They believed that Apple's use of Mac OS 9 as the default booting operating system on new computers illustrated their point. Apple switched to using Mac OS X as the default with the 10.1.2 release.
