Problems with Wireless Communication
If you have trouble using wireless communication:
 Make sure the computer or network you are trying to connect to is running and has a
wireless access point.
 Make sure you’ve properly configured the software according to the instructions that
came with your base station or access point.
 Make sure your iMac is 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 your iMac might
improve reception.
 Check the Wi-Fi status menu (Z) in the menu bar. Up to four bars appear, indicating
signal strength. If the signal strength is weak, try changing your location.
 See Help Center (click Help in the menu bar and search for “wi-fi”). Also see the
instructions that came with the wireless device for more information.
Keeping Your Software Up to Date
When you’re connected to the Internet, Software Update checks periodically to see
if updates are available for your computer. You can download and install these free
software versions, drivers, and other enhancements from Apple.
You can set how frequently your iMac checks for updates in Software Update
preferences. To check manually, choose Apple () > Software Update.
For more information about Software Update, see Help Center (click Help in the menu
bar and search for “Software Update”).
