Important safety information for your Mac

Handling. Set up your iMac on a hard, stable work surface that allows for adequate air circulation under and around the computer. Never push objects into the ventilation openings. Your iMac 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 iMac, such as one with a cracked screen, as it may cause injury.

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

Power. The only way to turn off power completely to your 24-inch iMac is to unplug the power cord from the wall outlet. For other iMac models, you can unplug the power cord either from the wall outlet or from your computer. Make sure the power cord is within easy reach so that you can unplug your iMac when you need to. Unplug the power cord (by pulling the plug, not the cord) and disconnect all cables if any of the following conditions exists:

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 iMac. Turn on the audio and check the volume before inserting anything into your ear. See Sound and Hearing.

Repairing. Your iMac should only be serviced by a trained technician. Disassembling your iMac may damage it or may cause injury to you. If you attempt to open your iMac, you risk damaging your computer, and such damage isn’t covered by the limited warranty on your iMac. If your iMac needs service, is damaged, malfunctions, or comes in contact with liquid, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device. You can find information about getting service at Mac Repair and Service.

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.

Medical device interference. iMac contains components and radios that emit electromagnetic fields. These electromagnetic fields may interfere with medical devices, such as pacemakers and defibrillators. Consult your physician and medical device manufacturer for information specific to your medical device and whether you need to maintain a safe distance of separation between your iMac and your medical device (more than 6 inches or 15 cm apart). If you suspect iMac is interfering with your medical device, stop using iMac and consult your physician and your medical device manufacturer.

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

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

High-consequence activities. Your iMac 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 iMac 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 iMac to environments having high concentrations of industrial chemicals, including evaporating liquified gases such as helium, may damage or impair iMac functionality.
