Input

• Magic Keyboard

  • The redesigned Magic Keyboard comes standard with your iMac. It’s wireless and rechargeable (so you won’t be replacing batteries), with an ultracompact, edge-to-edge design that wastes no surface space. It has an improved scissor mechanism, optimized key travel, and a lower profile that increase control and comfort. And it pairs immediately with your iMac right out of the box.

• Magic Mouse 2

  • The new design of Magic Mouse 2 lets it glide more 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. So if you prefer to use a wireless mouse but want some of the benefits of Multi-Touch, Magic Mouse 2 is a great choice.

• 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 new design, along with a lower profile, makes it even more 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 0.05 B.

2. L _{p A,m} is the mean A-weighted sound pressure level measured at the operator position (rounded to the nearest 0.5 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: 1.6GHz dual-core Intel Core i5 processor, 8GB memory, 1TB hard drive, Intel HD Graphics 6000.
