Using an iPad as a second monitor for your Mac Mini is one of the easiest ways to boost your productivity. Whether you’re juggling multiple tasks, editing videos, or need extra screen real estate for work, this setup can streamline your workflow. Apple’s built-in Sidecar feature makes it simple, but even if your devices aren’t compatible with Sidecar, there are third-party options to get the job done. Let’s walk you through everything you need to know.

Understanding the Sidecar Feature

Apple introduced Sidecar to make it effortless for users to extend their workspace. With this feature, your iPad acts like an extension of your Mac. It’s seamless, wireless, and packed with functionality. Let’s dive deeper.

What is Sidecar?

Sidecar is a feature that came with macOS Catalina and iPadOS 13, allowing your Mac to use an iPad as a secondary screen. It’s more than just a second monitor; your iPad also functions as a touchscreen, which makes it especially handy for creative tasks like drawing or photo retouching.

The feature supports both wired and wireless connections, meaning you can enjoy the convenience of mobility or rely on a cable for a more stable connection. Importantly, Sidecar isn’t just a mirror of your Mac’s display—it can act as an entirely separate screen, giving you the flexibility to drag apps, windows, and tools across displays.

Requirements for Using Sidecar

Before you jump in, you’ll need to make sure your devices support Sidecar. Here’s what you’ll need:

Compatible Mac Models:

• Mac Mini (2018 or newer)
• Running macOS Catalina or later

Compatible iPad Models:

• Any iPad Pro
• iPad (6th generation or newer)
• iPad Mini (5th generation or newer)
• iPad Air (3rd generation or newer)
• Running iPadOS 13 or later

Other Requirements:

• Both devices must be logged into the same Apple ID.
• Bluetooth, Wi-Fi, and Handoff must be enabled.
• For a wired connection, you’ll need a Lightning-to-USB or USB-C cable.

Setting Up Your iPad as a Second Monitor

Now that you know what you’ll need, let’s set up Sidecar step by step.

Checking Compatibility

First, ensure both devices meet the requirements listed above. You can check your macOS version by clicking on the Apple logo in the top-left corner of your Mac screen and selecting “About This Mac.” Similarly, verify your iPadOS version in “Settings > General > About.”

If your Mac and iPad don’t meet these requirements, skip ahead to the alternative solutions section below.

Connecting Devices via Sidecar

It’s time to pair your devices and extend your desktop:

1. Enable Bluetooth, Wi-Fi, and Handoff:
   On both devices, ensure Bluetooth and Wi-Fi are turned on. Then, go to “System Preferences > General” on your Mac and check the box next to “Allow Handoff.” On your iPad, toggle Handoff on under “Settings > General > AirPlay & Handoff.”
2. Connect Wirelessly:
   • On your Mac, click the Control Center icon (or go to “System Preferences > Displays”).
   • Select your iPad from the “Connect to” menu under Sidecar.
   • Your iPad will instantly transform into an extended display.
3. For a Wired Connection:
   • Plug your iPad into your Mac using the USB cable.
   • Follow the same steps to select your iPad from the Sidecar menu.

Adjusting Display Settings

Once Sidecar is running, you can customize the setup to your liking:

• Arrangement: Go to “System Preferences > Displays” on your Mac. Drag and position the icons to determine how your displays are arranged physically.
• Resolution and Scaling: Adjust text size and resolution under the Display preferences.
• Input Options: Use your Apple Pencil on the iPad to interact with your Mac apps. You can also show the Sidebar or Touch Bar on your iPad by enabling them in “Sidecar settings.”

Third-Party Alternatives to Sidecar

Not all Mac Mini and iPad models support Sidecar. Luckily, third-party apps are here to help, offering similar functionality.

Popular Third-Party Apps

1. Duet Display:
   Duet Display is a highly-rated app that works with most Mac and iPad models. It’s easy to set up, supports both wired and wireless connections, and provides smoother performance when connected via cable. It’s affordable, with a one-time fee for the basic version and additional features available via subscription.
2. Luna Display:
   Luna Display offers a seamless experience by using a small dongle. It connects wirelessly and even converts iPads into a touchscreen Mac display. Luna Display is more expensive than Duet but is known for its sharp performance and minimal lag.

How to Use Third-Party Apps

Here’s how you can set up one of these apps:

1. Download the app on both your Mac Mini and iPad from the App Store or the app’s website.
2. Follow the installation prompts, making sure both devices are on the same Wi-Fi network if using a wireless setup.
3. Launch the app, and your devices should sync automatically. If not, follow the troubleshooting tips provided within the app.

Pros and Cons of Third-Party Solutions

Pros:
