Chapter 29. Solving Mac Problems > Assessing Your Mac

Assessing Your Mac

Key to troubleshooting and solving problems that you can't prevent is being able to accurately and precisely assess how your Mac is performing and knowing the specific configuration of your system. Mac OS X offers many more diagnostic tools than previous versions of the OS did; however, several of these tools are quite complicated. Still, even if you are not able to interpret all their output, people who are trying to help might be able to, so even in this case it is useful for you to know how to use them. You should understand how to use these tools before you need them.

NOTE

If you choose Apple menu, About This Mac, you will see a window displaying the version of the Mac OS X you are running, the amount of RAM installed in your machine, and the specific processors it contains. You can also click the Software Update button to move to that pane in the System Preferences application or click More Info to move into the System Profiler. In Mac OS 9 and earlier, you could also get information about the RAM allocations for the applications running on your machine, switch among applications, and so on. Because Mac OS X manages RAM for you, this information is no longer valid, so the About This Mac window no longer serves the purposes it once did. However, for a quick insight into these major system parameters, it is a useful reference.
