Universal Control is a feature that allows you to use a single keyboard, mouse, or trackpad to control up to two other nearby Mac or iPad devices, and work seamlessly between them1. When using Universal Control, you can share the following peripherals between iPad and Mac:
* Trackpad: You can use the trackpad of your Mac or iPad to move the pointer across the screens of both devices. You can also use gestures to scroll, zoom, or switch between apps2.
* Keyboard: You can use the keyboard of your Mac or iPad to type on both devices. You can also use keyboard shortcuts to perform actions or access menus3.
* Mouse: You can use the mouse of your Mac to move the pointer across the screens of both devices. You can also use the mouse buttons to click or right-click4.
You cannot share the following peripherals between iPad and Mac when using Universal Control:
* Apple Pencil: You can only use the Apple Pencil on your iPad, not on your Mac. The Apple Pencil is designed to work with the touch screen of the iPad, not with the display of the Mac5.
* Touch ID: You can only use Touch ID on the device that has the Touch ID sensor, not on the other device. Touch ID is a biometric security feature that requires your fingerprint to unlock your device, make purchases, or use Apple Pay. References: = Universal Control: Use a single keyboard and mouse
