Chapter 7: History, Installing and Use of the MacOS
By Christine Schmied
Since 1979, Steve Jobs and the other hippies working with him in Cupertino have come up with some pretty wacky things. However, amongst the craziest was for a computer company that makes hardware to not make their hardware work with someone elses operating system, but make their own operating system to support it. It all began with the Lisa84, and System 1.0, the first Apple computer Operating System. Since then, they have evolved into Mac OS X quite rapidly, in this order:
As of this writing, the latest version of Mac OS X has been announced (10.4 aka Tiger) but has not been made available to the public.
What makes Mac OS X unique is that not only is it the first real replacement instead of upgrade for the older OS, it is also based on the FreeBSD UNIX operating system. Moreover, they were clever enough to add Carbon libraries, which allow applications based on older operating systems to run smoothly in Mac OS X and utilize its advantages. Mac OS X also includes the Classic environment, which allows those programs written for operating systems from System 7.x to OS 9.x to run within Mac OS X without any special upgrades.
The other two environments included in Mac OS X are Java, for Java native applications and Cocoa, for applications written strictly for use with Mac OS X.
