Boost Your Mac Workflow with macOS Universal Control

Introduction

The author upgraded to macOS 12.3 and explored the new "Universal Control" feature, finding it dramatically improves productivity when using multiple Apple devices.

Current Setup

Two MacBook Pros are used—a 2017 Intel model and a 2021 M1 Pro—connected to a 34‑inch Dell monitor.

Pain Points Before Universal Control

Keyboard/Mouse Switching : Using Logitech MX Keys and MX Master keyboards/mice requires manual Bluetooth switching, which can be cumbersome. The Logitech Flow feature was tried but proved unstable.

File Transfer : Transferring files between machines typically involves communication apps, USB drives, shared folders, or NAS sync. The author uses Synology NAS synchronization across all devices.

Enabling Universal Control

Ensure macOS is updated to the latest version (12.3) and iPadOS to 15.4 if using an iPad.

Log in with the same iCloud account on all devices.

Open System Preferences → Displays and locate the "Universal Control" button.

Check the box to enable Universal Control.

In the "Add Display" section, select nearby Apple devices to add them.

Arrange the displays to match the physical layout; drag to adjust positions.

After setup, moving the cursor to the edge of one screen automatically switches the keyboard to the adjacent device, and files can be dragged directly between screens.

Benefits After Activation

The workflow becomes fluid: no more pressing device‑switch buttons, and file transfers are as simple as dragging and dropping, eliminating the need for external transfer tools.

For non‑Apple users, Logitech Flow remains a viable alternative for seamless device switching.
