The operating system was handed out for free by Apple employees afterSteve Jobs'keynote speech at the Seyboldpublishing conference inSan Francisco. It was subsequently distributed toMac users on October 25, 2001, atApple Stores and otherretail stores that carried Apple products.
Mac OS X 10.1 was codenamed "Puma" because the internal team thought it was "one fast cat."[3] 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, replacingMac OS 9.[4]
More printer support (200 printers supported out of the box)— One of the main complaints of version 10.0 users was the lack of printer drivers, and Apple attempted to remedy the situation by including more drivers, although many critics complained that there were still not enough.
Faster 3D (OpenGL performs 20% faster)— The OpenGL drivers and handling were vastly improved in this version of Mac OS X, which created a large performance gap for 3D elements in the interface, and 3D applications.
ImprovedAppleScript— The scripting interface now allows scripting access to many more system components, such as the Printer Center, and Terminal, thus improving the customizability of the interface. As well, Apple introducedAppleScript Studio, which allows a user to create full AppleScript applications in a simple graphical interface.
Improved filehandling - TheFinder was enhanced to optionally hidefile extensions on a per-file basis. TheCocoa API was enhanced to allow developers to set traditional Mactype and creator information directly without relying on Carbon to do it.[5]
