What You've Learned

• The Apple General Troubleshooting Flowchart is an example of a well-defined troubleshooting methodology to use whenever you diagnose issues.

• Pick the tools that are most appropriate for the issue you are troubleshooting, whether they are network tools, system tools, or file-system tools.

• Early detection of suspicious activity or issues can eliminate or reduce the damage that might be incurred if things go undetected.

• Scripts are powerful tools you can use to automate functions you want performed on a regular basis, as well as to monitor your computer. Scripts are an integral part of any system administrator's repertoire.

• Mac OS X allows you to customize startup using startup items, which are scripts invoked at system startup, and through login hooks, which are scripts invoked when a user logs in from the login window.
