Managing Processes Graphically: Activity Monitor
As you know, pressing Option-Command-Escape opens a process list and enables you to force-quit open applications from the Tiger Finder. This is fine for many end-user applications, but doesn't provide the same depth of features that you can get from the command-line process management utilities.
For those seeking more control, Apple's Activity Monitor application (path: /Applications/Utilities/Activity Monitor) provides information on all the system's processes, not just the GUI software that is running; consider it a much-improved graphical version of the top command discussed earlier in this chapter.
Figure 12.2 shows the default Activity Monitor display.
