Important handling information for your Mac
Operating environment. Operating your iMac outside these ranges may affect performance:
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -40° to 116° F (-40° to 47° C)
Operating altitude: Tested up to 16,404 feet (0 to 5000 meters)
Do not operate your iMac in areas with significant amounts of airborne dust, or smoke from cigarettes, cigars, ashtrays, stoves, or fireplaces, or near an ultrasonic humidifier using unfiltered tap water. Tiny airborne particles produced by smoking, cooking, burning, or using an ultrasonic humidifier with unfiltered water may, in rare instances, enter the ventilation openings of your iMac and, under certain conditions, result in a slight haze on the inside surface of the glass panel that covers the iMac display.
Carrying your iMac. Before you lift or reposition your iMac, shut it down and disconnect all cables and cords. To lift your iMac, hold its sides.
Using connectors and ports. Never force a connector into a port. Before you plug the power cord into the power port, make sure the power port is completely free of debris. When connecting a device to a port, make sure the port is completely free of debris, that the connector matches the port, and that you have positioned the connector correctly in relation to the port.
Important: Use only the original cables that came with your computer or accessory, or cables sold at an Apple retail store or online at apple.com.
Storing your iMac. If you are going to store your iMac for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C).
Cleaning your iMac. When cleaning the outside of your iMac and its components, first shut down your iMac, then unplug all cords and cables. Then dampen a clean, soft, lint-free cloth to wipe the iMac exterior. Avoid getting moisture in any openings. Don’t spray liquid directly on the computer. Don’t use alcohol, aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide that might damage the exterior finish.
Cleaning the display. To clean the display, first shut down your iMac, then unplug all cords and cables. Dampen a clean, soft, lint-free cloth with just water and wipe the screen. Don’t spray liquid directly on the screen.
If your iMac display has standard glass, clean it using the included polishing cloth or a microfiber cloth and water.
Cleaning the Magic Keyboard or Magic Mouse. Turn off the device, then unplug the cable (if necessary). To clean the outside of your mouse or keyboard, use a clean, soft, lint-free cloth that’s been lightly moistened with water. Don’t get moisture in any openings or use aerosol sprays, solvents, or abrasives.
