MouseMagic 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.
TrackpadMagic 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.

It s wireless and rechargeable (so you won t be replacing batteries), with an ultra-compact, edge-to-edge design that wastes no surface space. It has an improved scissor mechanism, optimised key travel and a lower profile that increase control and comfort. And it pairs immediately with your iMac straight out of the box.
