Universal Control is a feature developed by Apple that allows users to control multiple devices seamlessly using a single mouse and keyboard. This means you can move your cursor between a Mac and an iPad without needing to switch settings or use different input devices. It enhances productivity by enabling users to drag and drop files between devices effortlessly. To use Universal Control, both devices must be signed into the same Apple ID and be within close proximity. The feature is designed to create a more integrated experience for users who work across different Apple devices, making multitasking smoother and more efficient.
