Safety, handling, and support
Important safety information
WARNING:  Failure to follow these safety instructions could result in fire, electric shock, or other 
injuries, or damage to your MacBook
 Air or other proper
 ty. Read all safety information below 
before using your MacBook
 Air.
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 Air 
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 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

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, 
washbasins, bathtubs, shower stalls, and so on. Protect your MacBook Air from dampness, 
humidity, or wet weather, such as rain, snow, and fog. 
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 
information provided on your MacBook Air 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 Air and always use common sense.

Charging. Charge MacBook Air only with the included 45W MagSafe 2 Power Adapter, or with 
other third-party cables and power adapters that are compatible with MagSafe 2 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 Air or other property. When you use the included  
45W MagSafe 2 Power Adapter to charge your MacBook Air, make sure the AC plug or AC power 
cord is fully inserted into the power adapter before you plug the adapter into a power outlet.
Prolonged heat exposure. 
Your MacBook Air and its 45W MagSafe 2 Power Adapter may become 
very warm during normal use. The MacBook Air and its 45W MagSafe 2 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.

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 Air on a pillow, blanket, or other soft material that can block ventilation openings. It’s 
important to keep your MacBook Air and its 45W MagSafe 2 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 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.
45W MagSafe 2 Power Adapter. To operate the 45W MagSafe 2 Power Adapter safely and reduce 
the possibility of heat-related injury or damage, do one of the following:
 •Plug the 45W MagSafe 2 Power Adapter directly into a power outlet.
 •If you’re using the AC power cord, place the power adapter on a desk, table, or on the floor in a 
well-ventilated location.
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 Air or 45W MagSafe 2 Power Adapter is exposed to rain, excessive moisture, or 
liquid spilled into the case.
 •Your MacBook Air or 45W MagSafe 2 Power Adapter has been dropped, the case has been 
damaged, or you suspect that service or repair is required.
The MagSafe 2 port (where you put in the MagSafe 2 connector) contains a magnet that can 
erase data on a credit card, iPod, or other device. To preserve your data, do not place these or 
other magnetically sensitive material or devices within 1 inch (25 mm) of this port.
If debris gets onto the MagSafe 2 port, remove it gently with a dry cotton swab.

Understanding ergonomics
When you use the keyboard and mouse, your shoulders should be relaxed. Your upper arm and 
forearm should form an angle that is slightly greater than a right angle, with your wrist and hand 
in roughly a straight line.
Not this
This
Use a light touch when typing or using the trackpad and keep your hands and fingers relaxed. 
Avoid rolling your thumbs under your palms.
Not this
This
Change hand positions often to avoid fatigue. Some computer users might develop discomfort 
in their hands, wrists, or arms after intensive work without breaks. If you begin to develop 
chronic pain or discomfort in your hands, wrists, or arms, consult a qualified health specialist.
External mouse. If you use an external mouse, position the mouse at the same height as the 
keyboard and within a comfortable reach.
Chair. An adjustable chair that provides firm, comfortable support is best. Adjust the height of 
the chair so your thighs are horizontal and your feet are flat on the floor. The back of the chair 
should support your lower back (lumbar region). Follow the manufacturer’s instructions for 
adjusting the backrest to fit your body properly.
Built-in display. Adjust the angle of the display to minimize glare and reflections from overhead 
lights and windows. Do not force the display if you meet resistance. The display is not designed 
to open past 135 degrees.
You can adjust the brightness of the screen when you take the computer from one work location 
to another, or if the lighting in your work area changes.
