History: Released in September 2001, Mac OS X 10.1 was a major step from Mac OS X 10.0. While Mac OS 10.0 felt like another beta, 10.1 was the first OS X release which could actually be used. Application launch time, window resizing and menus were significantly faster, the Dock was moveable, more customizable interface, enhanced 3D graphics performance, hundreds of drivers for third-party printers, cameras, camcorders, MP3 players and storage devices and additional network integration just to name a few of the new or improved features. Mac OS X 10.1 was a free upgrade for owners of Mac OS X 10.0. However, due to its size it was not available via Internet download, but could either be order directly from Apple for $20 or was available in the Apple Stores on burned CD-Rs.
