Read the 27-inch iMac with 5K Retina Display Environmental Report to learn more about its environmental performance.

sound performance

The declared value of noise emission complies with ECMA-109 standard

	Sound power level L W A,m (B)	Sound pressure level Operator position L p A,m (dB)
idle	2.3 (K v = 0.3)	13
Wifi	2.3 (K v = 0.3)	13

L W A,m means the mean value of the A-weighted sound power level (rounded to the nearest 0.1 B).
L p A,m represents the mean value of the A-weighted sound pressure levels measured at the operator's position (rounded to the nearest 1 dB).
1 B (bel) = 10 dB (decibels).
Kv denotes a statistical adder used to calculate the upper limit of the A - weighted sound power level.
The amount of L W A,c (formerly called L W Ad ) can be calculated from the sum of L W A,m and K v .
The Wi-Fi test browsed 25 major websites.
Configuration tested: 3.8GHz 8-core Intel Core i7 processor, 8GB RAM, 512GB storage, Radeon Pro 5500 XT graphics.

1GB = 1 billion bytes, 1TB = 1 trillion bytes; actual formatted capacity may be less.
Weight may vary by configuration and manufacturing process.
iMovie, GarageBand, Pages, Numbers, and Keynote are available on the Mac App Store. Downloading apps requires an Apple ID and a device compatible with the OS version required by each app.
Data accurate as of product release.
Apple products are free of polyvinyl chloride (PVC) and phthalates, except for AC power cords in India, Thailand (for dual-prong AC power cords), and South Korea. In these countries, local government approval for our polyvinyl chloride (PVC) and phthalate alternatives is still pending.
The 21.5-inch iMac with 4K Retina display and 27-inch iMac with 5K Retina display final assembly supplier facility is third-party certified to meet UL LLC's Zero Waste to Landfill standard (UL 2799 standard).
