Apple's Sidecar feature lets you use your iPad as an external display with your Mac. This is useful when you want an extra screen but don't want to put a monitor on just for that. However, users find it frustrating to use Sidecar as it often does not work. Here are the top 8 ways to fix Sidecar not working on your Mac and iPad.




Remember that Sidecar is different from Universal Control. Universal Control lets you use a single keyboard and mouse as input sources for iPad and Mac. Meanwhile, Sidecar turns your iPad into a secondary display for your Mac.

1. Check device compatibility

Sidecar functionality is limited to certain Macs running macOS Catalina or later, and iPads must be running at least iPadOS 13 or later. Before you start troubleshooting, check whether your Mac and iPad are running the latest software and compatible or not. Below is the list of compatible devices.

Mac compatibility

  • MacBook Pro (2016 or later models)
  • MacBook (2016 and later)
  • MacBook Air (2018 or later models)
  • iMac (2017 or later models)
  • iMacPro
  • Mac mini (2018 or later models)
  • Mac Pro
  • mac studio

iPad compatibility

  • iPad Pro (all models)
  • iPad (6th generation or later)
  • iPad mini (5th generation or later)
  • iPad Air (3rd generation or later)

2. Verify your Apple ID

Using the same Apple ID on Mac and iPad is one of the main requirements to use the Sidecar feature. So, your iPad and your Mac must have the same Apple ID account. Here's how to check if you have the same ID on both.

Mac
