WARNING: Failure to follow these safety instructions could result in fire, electric shock, or other injuries, or damage to your MacBook or other property. Read all safety information below before using your MacBook.
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 lithium-ion battery in your MacBook should be replaced by Apple or an authorized service provider, and must be recycled or disposed of separately from household waste. Don’t expose your MacBook 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 with care. It is made of metal, glass, and plastic and has sensitive electronic components inside. Place your MacBook on a stable work surface that allows for adequate air circulation under and around the computer. Your MacBook 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, such as one with a cracked screen, as it may cause injury.
Liquid exposure. Keep your MacBook away from sources of liquid, such as drinks, oils, lotions, washbasins, bathtubs, shower stalls, and so on. Protect your MacBook from dampness, humidity, or wet weather, such as rain, snow, and fog.
Repairing. Your MacBook doesn’t have any user-serviceable parts. Do not open or disassemble MacBook or attempt to repair it or replace any components. Disassembling your MacBook may damage it or may cause injury to you. If your MacBook 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, you risk damaging your computer, and such damage isn’t covered by the limited warranty on your MacBook.
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 information provided on your MacBook 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 laws and regulations in the areas where you are using your MacBook and always use common sense.
Charging. Charge MacBook only with the included 29W USB-C Power Adapter, or with other third-party cables and power adapters that are compatible with USB-C and are compliant with applicable regulations.
Using damaged cables or chargers, or charging when moisture is present, can cause fire, electric shock, injury, or damage to your MacBook or other property. When you use the included 29W USB-C Power Adapter to charge your MacBook, make sure the USB-C Charge Cable (2m) is fully inserted into the power adapter before you plug the adapter into a power outlet.
Prolonged heat exposure. Your MacBook and its 29W USB-C Power Adapter may become very warm during normal use. The MacBook and its 29W 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.
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. Don’t operate your MacBook on a pillow, blanket, or other soft material that can block ventilation openings. It’s important to keep your MacBook and its 29W USB-C Power Adapter in a well-ventilated area when in use or charging.
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. If your MacBook 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.
29W USB-C Power Adapter. To operate the 29W USB-C Power Adapter safely and reduce the possibility of heat-related injury or damage, do one of the following:
Plug the 29W USB-C Power Adapter directly into a power outlet.
If you’re using the Power Adapter Extension Cable, place the power adapter on a desk, table, or on the floor in a well-ventilated location.
Don’t use a power adapter in wet locations, such as near a washbasin, bathtub, or shower stalls, or connect or disconnect the power adapter with wet hands. Disconnect the power adapter and any cables if any of the following conditions exists:
You want to clean the case (use only the recommended procedure, described in Important handling information).
The power cord or plug becomes frayed or otherwise damaged.
Your MacBook or 29W USB-C Power Adapter is exposed to rain, excessive moisture, or liquid spilled into the case.
Your MacBook or 29W USB-C Power Adapter has been dropped, the case has been damaged, or you suspect that service or repair is required.

Take special care if you have a physical condition that affects your ability to detect heat against the body.
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. Turn on the audio and check the volume before inserting anything into your ear. For more information about hearing loss, see Sound and Hearing.
WARNING: To prevent possible hearing damage, do not listen at high volume levels for long periods.
Radio frequency exposure. MacBook 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, see RF Exposure.
Medical device interference. MacBook contains components and radios that emit electromagnetic fields, which may interfere with pacemakers, defibrillators, or other medical devices. Maintain a safe distance of separation between your medical device and MacBook. Consult your physician and medical device manufacturer for information specific to your medical device. If you suspect MacBook is interfering with your pacemaker or any other medical device, stop using MacBook.
Medical conditions. If you have a medical condition that you believe could be affected by using MacBook (for example, seizures, blackouts, eyestrain, or headaches), consult with your physician prior to using MacBook.
Repetitive motion. When you perform repetitive activities such as typing or playing games on MacBook, you may experience discomfort in your hands, arms, wrists, shoulders, neck, or other parts of your body. If you experience discomfort, stop using MacBook and consult a physician.
Choking hazard. Some MacBook accessories may present a choking hazard to small children. Keep these accessories away from small children.
High-consequence activities. Your MacBook is not intended for use where the failure of the computer could lead to death, personal injury, or severe environmental damage.
Explosive atmospheres. Charging or using your MacBook in any area with a potentially explosive atmosphere, such as areas where the air contains high levels of flammable chemicals, vapors, or particles (such as grain, dust, or metal powders), may be hazardous. Obey all signs and instructions.
