If you've tried to screen mirror your iPad to your Mac but hit a wall because the devices use different Apple IDs, you’re not alone. Apple’s built-in Sidecar and AirPlay features work great—until they don’t. One common frustration? Sidecar doesn’t support iPads and Macs signed in with different Apple IDs.

So what are your options?

In this guide, we’ll break down:

• Why Sidecar and AirPlay fall short for cross-Apple ID use
• Workarounds that actually work
• The best solution for seamless screen mirroring: Duet Display

Why Can't I Use Sidecar with Different Apple IDs?

Apple’s Sidecar and AirPlay are designed to work within a single iCloud ecosystem. This means:

• Both your iPad and Mac must be signed in with the same Apple ID
• You need two-factor authentication enabled
• Devices must be on the same Wi-Fi network
  
  

So if you’re using a work Mac and a personal iPad, or sharing devices across family or teammates, you’ll likely get hit with the “Device Not Available” error—or the devices just won’t connect.

Common Workarounds (and Why They Fall Short)

There are a few things people try:

• Signing in and out of Apple IDs – Not ideal, especially if you use iCloud Photos or app syncing.
• AirPlay screen recording tools – Can introduce lag and security concerns.
• Using a third-party remote desktop app – Not built for high-resolution mirroring or stylus input.

These options can be clunky or break the Apple user experience entirely.

The Best Alternative: Duet Display

If you need a reliable, high-performance way to mirror your iPad to your Mac—even across different Apple IDs—Duet Display is a great solution.

Here’s why Duet works when Sidecar doesn’t:

• No Apple ID dependency – Duet connects devices regardless of iCloud accounts.
• Works with macOS + iOS, Windows + Android – Great for hybrid users.
• Wired and wireless options – Use USB for zero lag or Wi-Fi for flexibility.
• Touch & Apple Pencil support – Ideal for creatives and remote professionals.

Whether you’re presenting, editing, teaching, or just want a second screen, Duet turns your iPad into an instant monitor—without jumping through Apple’s hoops.

Pro tip: Duet works great for businesses or classrooms where users can’t or shouldn’t share Apple IDs.

2. Install the app on both devices.
