Important handling information for your Mac
Operating environment. Operating your MacBook Air outside these ranges may affect performance:
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -13° to 113° F (-25° to 45° C)
Relative humidity: 0% to 90% (noncondensing)
Operating altitude: Tested up to 10,000 feet (0 to 3048 meters)
Carrying your MacBook Air. If you carry your MacBook Air in a bag or briefcase, make sure there are no loose items (such as paper clips or coins) that could accidentally get inside the computer through vent openings or get stuck inside the USB-C ports.
Using connectors and ports. Never force a connector into the USB-C ports. When connecting a device, make sure the port is free of debris, that the connector matches the port, and that you have positioned the connector correctly in relation to the port.
Using the USB-C Charge Cable (2 m). Certain usage patterns can contribute to the fraying or breaking of cables. The USB-C Charge Cable, pictured in What’s included, like any other metal wire or cable, is subject to becoming weak or brittle if repeatedly bent in the same spot. Aim for gentle curves instead of angles in the cable. Regularly inspect the cable and connectors for any kinks, breaks, bends, or other damage. Should you find any such damage, discontinue use of the USB-C Charge Cable.
Storing your MacBook Air. If you’re going to store your MacBook Air for an extended period of time, keep it in a cool location (ideally, 71° F or 22° C) and discharge the battery to 50 percent. When storing your computer for longer than five months, maintain the capacity of the battery by charging the battery to 50 percent every six months or so.
Cleaning your MacBook Air. When cleaning the outside of your MacBook Air and its components, first shut down your MacBook Air, then unplug the 30W USB-C Power Adapter. Then dampen a clean, soft, lint-free cloth to wipe the MacBook Air exterior. Avoid getting moisture in any openings. Don’t spray liquid directly on the computer. Don’t use aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide that might damage the finish.
Cleaning the MacBook Air screen. To clean the MacBook Air screen, first shut down your MacBook Air and unplug the 30W USB-C Power Adapter. Dampen a clean, soft, lint-free cloth with just water and wipe the screen. Don’t spray liquid directly on the screen.
