<strong>OS</strong> X <strong>Support</strong> <strong>Essentials</strong> <strong>10.8</strong> Exam Preparation Guide<br />
4. When performing a Safe Boot, <strong>OS</strong> X doesn’t load third-party<br />
KEXTs, third-party launch agents, third-party launch<br />
daemons, third-party startup items, third-party fonts, any user<br />
login items, or any user-specific launch agents.<br />
5. If an issue disappears when a Safe Boot is successful, you<br />
must find and remove the third-party startup resource that<br />
caused the issue. The best way to isolate the problem is to<br />
start up the Mac in Verbose mode and then observe where<br />
the startup process fails. Verbose mode is initiated by holding<br />
down Command-V during system startup.<br />
