Chapter 2 Getting to Know Your iMac 35
Using Applications
Your iMac comes with iLife applications and other software applications for sending
email, surfing the Internet, chatting online, organizing music and digital photos,
making movies, and much more. For information about these applications, open the
application, then open Mac Help for the application.
When an Application Doesn’t Respond
On rare occasions, an application may “freeze” on the screen. Mac OS X provides a way
to quit an application that’s not responding without restarting your iMac. Quitting a
frozen application may allow you to save your work in other open applications.
To force an application to quit:
1 Press Command (x)-Option-Esc or choose Apple () > Force Quit.
The Force Quit Applications dialog appears with the application selected.
2 Click Force Quit.
The application quits, leaving all other applications open.
