  1. L W A,m is the mean A-weighted sound power level, rounded to the nearest 0.1 B.

  2. L p A,m is the mean A-weighted sound pressure level measured at operator position (rounded to the nearest 1 dB).

  3. 1 B (bel) = 10 dB (decibel)

  4. K v is the statistical adder for computing upper-limit of A-weighted sound power level.

  5. The quantity, L W A,c (formerly called L W Ad) may be computed from the sum of L W A,m and K v .

  6. The Wireless web test browses 25 popular websites.

  7. Configuration tested: 3.0GHz 6-core Intel Core i5 processor, 8GB memory, 1TB Fusion drive, Radeon Pro 560X Graphics.

  1. 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less.

  2. Weight varies by configuration and manufacturing process.

  3. iMovie, GarageBand, Pages, Numbers, and Keynote are available on the Mac App Store. Downloading apps requires an Apple ID and a device that is compatible with the OS version required for each app.

  4. Data accurate as of product launch.

  5. Every Apple product is free of PVC and phthalates with the exception of AC power cords in India, Thailand (for two-prong AC power cords), and South Korea, where we continue to seek government approval for our PVC and phthalates replacement.

  6. Final assembly supplier sites for 21.5-inch iMac with Retina 4K display and 27‑inch iMac with Retina 5K display are third-party certified as Zero Waste by UL LLC (UL 2799 Standard).
