For some users, the iPad does not appear in Sidecar. As per reports, the problem occurs during wireless and wired connections.

Although I have not had such problems on my Mac, I can see the culprits behind this issue-primarily based on my experience.

So, if you are looking for the solution of Sidecar that does not work, you are the right problem-solving folder. Let’s get rid of the hook immediately!

How to fix iPad that doesn’t appear in the Sidecar problem

  • Make sure your devices are compatible

Although this is not a solution per se, it is worth repeating that not all maces and Ipades are working with Sidecar – even if they have the support for macOS Catalina and iPadOS respectively. So, make sure your devices are fully on board before trying this feature.

  • 12.9-inch iPad Pro
  • 11-inch iPad Pro
  • IPad Pro of 10.5 inches
  • IPad Pro of 9.7 inches
  • iPad Air (3rd sex)
  • iPad (6th-gen or later)
  • 5th Gen iPad iPad

  • MacBook 2016 or later
  • Mac Pro 2019 or later
  • iMac Pro 2017 or later
  • iMac 2015 or later
  • MAC Mini 2018 or later

Side Note: Although there is a complicated solution to use Sidecar, even on a Mac that isn’t supported, I don’t want to recommend it for a normal user, since it doesn’t work most of the time.

Keep Two-Factor Authentication Enabled

Apple had two-factor authentication to have made for most new features such as messages in iCloud. It is expected that the story is not different for Sidecar. So, if you’ve turned off 2FA, make sure you can use Sidecar.

On your iPad: Open settings → profile photo aka Avatar → password and security → two-factor authentication. Now, make sure it is enabled.

On Your Mac: Launch System Preferences → Apple ID → Password & Security → Two-Factor Authentication. Now, make sure 2FA option is ON.

Turn on/on Wi-Fi, Bluetooth and Handoff

Both of your devices must be on the same Wi-Fi connection for Sidecar to work. In addition, Bluetooth and Handoff must be activated on the iPad and Mac as well.

If you face the problem even after you’ve eliminated the essential subject Select, then try to turn off Wi-Fi, Bluetooth, and Handoff. And then restart your devices.

Disable Wi-Fi and Bluetooth

Click on your Mac on the Wi-Fi icon in the status bar and select Wi-Fi.

Turn Off Wi-Fi in macOS

Also, click on the Bluetooth icon and choose Turn Bluetooth Off.

Disable Bluetooth on Mac

On your iPad, head into the Settings app → Wi-Fi/Bluetooth. Now, turn them off.

Disable handOff

On your MAC: click on the Apple () menu → system preferences → general. Check the box for “allow checkout between this Mac and your iCloud devices. “

Turn Off Handoff on Mac

On your iPad: Head over to Settings → General → Handoff, then turn on Handoff.

Now restart both of your devices. After they start, turn Wi-Fi, Bluetooth and Handoff to Mac and iPad. Try to use Sidecar next time. Simply click on the AirPlay icon in the menu bar on your Mac, and then select the option to connect to your iPad. If it started working, it’s good to go.

Note: To use Sidecar Wireless, keep your devices down within 10 metres apart.

Ensure that your iPad and Mac do not share Internet

Sidecar will not work if your iPad and MAC are configured to share an Internet connection. Maybe your internet sharing on your device has made possible and forgot to eliminate it. Look at this because this might be the reason for this problem.

On your iPad, go to Settings → personal hotspot and then turn off the switch.

Open System Preferences → part on your Mac. Now, uncheck the Internet Sharing box.

Ensure that your iPad is set on trusting your MAC

Familiarise yourself especially using sidecar via USB, that your iPad is set on trusting your Mac. If you connect your iPad with a cable to the macOS device, a pop-up will appear on the tablet in which you are prompted to trust the computer. Tap Trust.

Just in case the pop-up to trust the computer does not appear, set the location and privacy again. Run Settings app on your iPad → general → set back. Now, tap restore location and privacy and confirm.

Disable block all incoming connections

Did your Firewall be turned on to your MAC? Slightly buried in the Firewall setting is the option to block all the incoming connections, except those required for basic Internet services such as IPSec, DHCP, Bonjour, etc. Since it is known that it creates problems with the connection, it is better to turn it off.

One thing you need to name is that you don’t have to turn off the firewall to disable this feature.

Open System Preferences → safety and privacy → Firewall tab. Now, click the Lock, and enter the user name password.
