If you have a problem with an application
 For a problem with software from a manufacturer other than Apple, contact the
manufacturer. Software manufacturers often provide updates to their software on
their websites.
You can check for and install the latest Apple software using the Software Update
pane of System Preferences. Your iMac is set to check automatically once a week but
you can set it to check daily or monthly. You can also check for updates manually. For
more information, choose Help > Mac Help and search for “software update.”
If you have trouble using AirPort wireless communication
 Make sure you have properly configured the software according to the instructions
that came with your AirPort Extreme Base Station or AirPort Express.
 Make sure the computer or network you are trying to connect to is running and has a
wireless access point.
 Make sure you are within antenna range of the other computer or the network’s
access point. Nearby electronic devices or metal structures can interfere with wireless
communication and reduce this range. Repositioning or rotating the iMac may
improve reception.
 Check the AirPort signal level. There are up to four bars in the AirPort status icon in
the menu bar.
 You may experience network performance problems if a microwave oven, cordless
telephone, or other source of interference is used near your base station. To minimize
interference, move the base station away from the device.
