• Magic Keyboard with Numeric Keypad
  You get all the functionality of Magic Keyboard, with an extended layout that makes it even easier to work and play. Magic Keyboard with Numeric Keypad includes document navigation controls — page up, page down, home, and end — and full-size arrow keys that are perfect for navigating pro apps, moving through spreadsheets, and playing games.
• Magic Mouse 2
  Magic Mouse 2 comes standard with your iMac. The design of Magic Mouse 2 lets it glide smoothly across your desk. And since it supports Multi-Touch, you can use simple gestures on its surface to do things such as swipe between web pages and scroll through documents.
• Magic Trackpad 2
  If you prefer using a trackpad, Magic Trackpad 2 gives you the full range of Multi-Touch gestures and introduces Force Touch to the desktop. Sensors underneath the trackpad surface detect subtle differences in the amount of pressure you apply, bringing more functionality to your fingertips and enabling a deeper connection to your content. This design, along with a low profile, makes it extremely comfortable to use.

Acoustic Performance

Declared noise emission values in accordance with ECMA-109

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: 2.3GHz dual-core Intel Core i5 processor, 8GB memory, 1TB hard drive, Intel Iris Plus Graphics 640.
