Once the Mac app is installed, you will need the corresponding app on your iPad or tablet. While the desktop client is a free download, the mobile app typically requires a purchase or a subscription. However, Duet frequently offers trial periods for their Pro and Air tiers. These trials allow you to experience professional features—like wireless connectivity, remote desktop access, and Apple Pencil pressure sensitivity—at no initial cost.

To begin your setup, you need to download the Mac companion app. This software acts as the bridge between your desktop and your mobile device. You can find the official Duet Display Mac free download directly on the Duet Display website. Simply navigate to the download section and select the macOS version. The installation process is straightforward: open the downloaded file, drag Duet to your Applications folder, and follow the on-screen prompts to grant necessary permissions.

The core appeal of Duet Display is its reliability. Unlike many wireless solutions that suffer from latency or connection drops, Duet provides a stable environment for multitasking. Whether you are coding, designing, or managing spreadsheets, having that extra screen real estate on your Mac is a game changer.
