Input

Magic Keyboard

Magic Keyboard comes standard with your iMac. It’s wireless and rechargeable (so you won’t be replacing batteries), with a remarkably compact edge-to-edge design that wastes no surface space. It has a stable scissor mechanism, optimised key travel and a low profile, providing control and comfort. And it pairs immediately with your iMac straight out of the box.

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-sized 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.
