• Unsupported devices: Sidecar isn't an option on all iPads and Macs. Confirm that your models are supported.

6. Check your iPad Bluetooth settings. There could be a Bluetooth communication issue between the devices. Try turning Bluetooth off and back on again on your Mac and iPad.

8. Try restarting both devices. Sometimes, a quick restart of your iPad or Mac can flush out communication issues or clear corrupted files from memory and get the systems talking to each other again.

9. Try plugging your iPad into the Mac. Use a USB cable to plug your iPad into your Mac to solve any wireless connection issues.

10. Check your iPad is a trusted device from two-factor authentication settings. If you added your iPad as a trusted device with two-factor authentication on your Mac, you should see it fromApplemenu >Settings>Apple ID>the list of trusted devices at the bottom of the screen.

11. Make sure your Mac isn't sharing its Wi-Fi connection. The same goes for your iPad sharing a cellular connection.

12. Clear a black screen. If you see a black screen, on your Mac, click theApple logo >System Settings>Displays> Arrangeand toggle the mirroring option on and off to reset it.
