System Profiler
As you learn in the next lesson, the first step in the troubleshooting flowchart is to gather information, and one of the best tools at your disposal is System Profiler, included with Mac OS X 10.3 and higher. A similar program, called Apple System Profiler, is included with Mac OS 8.6 through Mac OS X 10.2. Both programs gather detailed information about system software versions; types and number of hard drives and other peripherals; and installed memory, extensions, and applications.
NOTE
This lesson focuses on the latest version of System Profiler, but much of the same functionality is found in the earlier versions as well. You should use the version that matches the startup operating system for the Mac you're testing.
