This chapter will show what you'll seeand what to do when things don't seem to work right. Working with the Classic environment is a somewhat unusual experience.Depending on the application running, there can be graphic anomalies andconfusing file system navigation. Programshave much more breathing room in which to function. Tothe Classic environment, the virtual memory appears to be real memory.

Each Mac OS 9.x application can beconfigured for a much larger memory partition than was possible previously. On the other hand, Classic brings the benefit of Mac OS X's virtualmemory underpinnings to legacy applications. Users of 3Dfx video cards, hardware DVD playback, videocapture cards, and even some CD writers will find that their hardware no longerfunctions correctly. This means software that accesses hardwaredirectly will fail.

When using the Classic environment, the 9.x operating system must access allhardware through the Mac OS X kernel. In essence, you're booting two operating systemssimultaneously. Mac OS X must be running forClassic to work. When it comes to Classic, more is definitelybetter.Ĭlassic is a process under Mac OS X. You must have at least 128MB of memory to use Classic, and a 400MHz G3(or faster) is recommended. To Mac OS X, Classic is nothing but another application to a user, however,Classic is a gateway to his older software programs. The Classic EnvironmentĪs defined in Chapter 1, "Mac OS X Component Architecture," theClassic environment is a complete implementation of Mac OS 9.x on top of Mac OSX.

This chapter looks at the Classic environment, how it works, how to configure it, and what to do if you absolutely must boot into Mac OS 9.x. It is not a perfect solution, but it does allow for a high degree of compatibility with legacy hardware and software from within Mac OS X. It even allows certain pieces of hardware to be accessible, such as USB scanners and cameras.
Classic provides a runtime layer for older, non-Carbonized Mac applications.
To accommodate this need, Apple included the Classic environment. Those of you who have been using the Mac operating system regularly for years, however, are likely to already have a software library that you rely on. If you've never had a Mac or are a NeXT user who's happy to have finally found a home, Mac OS X probably has more than enough available software and functionality to make you happy.
