Important safety information for your Mac

Built-in battery. Don’t attempt to replace or remove the battery yourself—you may damage the battery, which could cause overheating and injury. The built-in battery should be replaced by Apple or an authorized service provider, and must be recycled or disposed of separately from household waste. Dispose of batteries according to your local environmental laws and guidelines. Don’t expose your MacBook Air to extreme heat sources, such as radiators or fireplaces, where temperatures might exceed 212°F (100°C).

For information about battery service and recycling, go to Battery Service and Recycling.

Handling. Handle your MacBook Air with care. It is made of metal, glass, and plastic and has sensitive electronic components inside. Place your MacBook Air on a stable work surface that allows for adequate air circulation under and around the computer. Your MacBook Air can be damaged if dropped, burned, punctured, or crushed, or if it comes in contact with liquids, oils, and lotions. Don’t use a damaged MacBook Air, such as one with a cracked screen, as it may cause injury.

Liquid exposure. Keep your MacBook Air away from sources of liquid, such as drinks, oils, lotions, sinks, bathtubs, shower stalls, and so on. Protect your MacBook Air from dampness, humidity, or wet weather, such as rain, snow, and fog.

Charging. Charge MacBook Air only with the included 30W USB-C Power Adapter and USB-C Charge Cable, or with a third-party power adapter and cable that are compatible with USB-C and compliant with applicable international and regional regulations and safety standards, including IEC 60950-1. Other power adapters might not meet applicable safety standards, and charging with such power adapters could pose a risk of death or injury.

Using damaged power adapters or cables, or charging when moisture is present, can cause fire, electric shock, injury, or damage to your MacBook Air or other property. When you use the included 30W USB-C Power Adapter and USB-C Charge Cable to charge your MacBook Air, make sure the USB-C Charge Cable is fully inserted into the power adapter before you plug the power adapter into a power outlet.

Prolonged heat exposure. Your MacBook Air and its 30W USB-C Power Adapter may become very warm during normal use. The MacBook Air and its 30W USB-C Power Adapter comply with applicable surface temperature standards and limits defined by the International Standard for Safety of Information Technology Equipment (IEC 60950-1). However, even within these limits, sustained contact with warm surfaces for long periods of time may cause discomfort or injury.

To reduce the possibility of overheating or heat-related injuries, always allow adequate ventilation around the MacBook Air or 30W USB-C Power Adapter and use care when handling them. Use common sense to avoid situations where your skin is in prolonged contact with a device or its power adapter when it’s operating or plugged into a power source. For example, don’t sleep with a device or power adapter when it’s plugged into a power source. Do not place the device or power adapter under a blanket, pillow, or your body when the device or adapter is connected to a power source. Never push anything into the ventilation openings, as doing so may be dangerous and cause your computer to overheat. Never place anything over the keyboard when operating your MacBook Air. If your MacBook Air is on your lap and gets uncomfortably warm, remove it from your lap and place it on a stable, well-ventilated work surface. Take special care if you have a physical condition that affects your ability to detect heat against the body.

30W USB-C Power Adapter. To operate the 30W USB-C Power Adapter safely and reduce the possibility of heat-related injury or damage, do one of the following:

Hearing loss. Listening to sound at high volumes may damage your hearing. Background noise, as well as continued exposure to high volume levels, can make sounds seem quieter than they actually are. Use only compatible earbuds, headphones, or earpieces with your MacBook Air. Turn on the audio and check the volume before inserting anything into your ear. See Sound and Hearing.

Repairing. Your MacBook Air doesn’t have any user-serviceable parts. Do not open or disassemble MacBook Air or attempt to repair it or replace any components. Disassembling your MacBook Air may damage it or may cause injury to you. If your MacBook Air needs service, is damaged, malfunctions, or comes in contact with liquid, contact Apple or an Apple-authorized repair center, such as an Apple Authorized Service Provider. If you attempt to open your MacBook Air, you risk damaging your computer, and such damage isn’t covered by the limited warranty on your MacBook Air.

Navigation. Maps, directions, and location-based apps depend on data services. These data services are subject to change and may not be available in all areas, resulting in maps, directions, or location-based information that may be unavailable, inaccurate, or incomplete. Compare the provided location-based information to your surroundings and defer to posted signs to resolve any discrepancies. Do not use these services while performing activities that require your full attention. Always comply with posted signs and the applicable laws and regulations in the areas where you are using navigation, and always use common sense.

Radio frequency exposure. MacBook Air uses radio signals to connect to wireless networks. For information about radio frequency (RF) energy resulting from radio signals and steps you can take to minimize exposure, go to RF Exposure.

Medical device interference. MacBook Air contains components and radios that emit electromagnetic fields, including magnets, which may interfere with pacemakers, defibrillators, and other medical devices. Maintain a safe distance between your medical device and MacBook Air. Consult your physician and medical device manufacturer for information specific to your medical device. If you suspect MacBook Air is interfering with your pacemaker or any other medical device, stop using MacBook Air.

Medical conditions. If you have a medical condition that you believe could be affected by using MacBook Air (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician prior to using MacBook Air.

Repetitive motion. When you perform repetitive activities such as typing or playing games on MacBook Air, you may experience discomfort in your hands, arms, wrists, shoulders, neck, or other parts of your body. If you experience discomfort, stop using MacBook Air and consult a physician.

Choking hazard. Some MacBook Air accessories may present a choking hazard to small children. Keep these accessories away from small children.

High-consequence activities. Your MacBook Air is not intended for use where the failure of the computer could lead to death, personal injury, or severe environmental damage.

Explosive and other atmospheric conditions. Using MacBook Air in any area with a potentially explosive atmosphere may be hazardous—particularly in areas where the air contains high levels of flammable chemicals, vapors, or particles such as grain, dust, or metal powders. Exposing MacBook Air to environments having high concentrations of industrial chemicals, including evaporating liquified gases such as helium, may damage or impair MacBook Air functionality.
