Hearing damage Permanent hearing loss may occur if earbuds or headphones are used at high volume. You can adapt over time to a higher volume of sound that may  sound normal but can be damaging to your hearing. Â

ÂÂ Limit the amount of time you use earbuds or headphones at high volume.
ÂÂ Avoid turning up the volume to block out noisy surroundings.
ÂÂ Turn the volume down if you can’t hear people speaking near you.
Operating environment Operating your iMac outside these ranges may affect performance:
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature:
Relative humidity: 5% to 90% (noncondensing)

Tiny airborne particles produced by smoking, cooking, burning, or using an ultrasonic humidifier with unfiltered water may, in rare instances, enter the ventilation openings of your iMac and, under certain conditions, result in a slight haze on the inside surface of the glass panel that covers the iMac display.
Turning on your iMac Never turn on your iMac unless all of its internal and external parts are in place. Operating your iMac when parts are missing may be dangerous and may damage your iMac.
