" 58 Chapter 3 CHAPTER 4 4 Working With Your Operating System An operating system, or OS, is the environment that defines how the items on your computer's desktop are represented and how you interact with them. Your computer comes with Mac OS X installed as the default operating system, and with Classic, an environment for using Mac OS 9 applications while the computer is running Mac OS X. To switch between Mac OS X and Mac OS 9, see "Switching Between Operating Systems" on page 61. Some software applications have not yet been optimized to work with Mac OS X or Classic. If you use only Mac OS 9­compatible software and do not need the special features of Mac OS X, you can start up your computer in Mac OS 9. This chapter describes some of the features of Mac OS X and Classic, and how to switch your default operating system from Mac OS X to Mac OS 9. 59 About Mac OS X Mac OS X advanced technologies include an elegant new user interface, incredible graphics capabilities, and added system stability and performance. Mac OS X manages your computer processes so you can concentrate on what you want to do. You don't need to restart your computer if something goes wrong with one software application--Mac OS X shuts down only that application so you can keep working without interruption. The Mac OS X virtual memory manager allots the amount of memory your software applications need to run efficiently. When you're ready to learn more about Mac OS X, read Welcome to Mac OS X, a book that introduces the features of Mac OS X and provides tips for using Mac OS X to perform common tasks. If you experience any problems while learning about Mac OS X, see the troubleshooting tips in the back of the book or choose Mac Help from the Help menu in Mac OS X. Because Mac OS X is already installed on your computer, you don't need to follow the installation instructions in Welcome to Mac OS X. You need to follow the instructions in Welcome to Mac OS X only to log in and begin using Mac OS X. Important Information About Software and Mac OS X For information about the compatibility of software applications with Mac OS X, or to read more about Mac OS X, check the Apple website: guide. apple. com/macosx/ Using Classic in Mac OS X In addition to using Mac OS X applications, you can continue to use Mac OS 9 applications in the Classic environment. Classic works in the background to access Mac OS 9 features and software applications. When you start up Classic, Mac OS 9 software works in Mac OS X just as it does in Mac OS 9, but doesn't benefit from Mac OS X features such as the look of the new interface. Simply open a Mac OS 9 application or double-click a document created in a Mac OS 9 application. Classic continues to run in the background, even if no Mac OS 9 applications are open, so applications and documents open faster and more easily. You can set your computer to start up Classic automatically when you log in to Mac OS X. In the Apple (K) menu, choose System Preferences, click Classic, and select "Start Classic when you log in. " To quit the Classic environment, click Stop in the Classic pane of System Preferences.
