Sidecar is a popular feature of macOS Catalina that lets you use a compatible iPad as a secondary display. This allows you to mirror your Mac’s content or extend your display for more screen space on the go.

To be able to use Sidecar, you just need to have a compatible iPad running iOS 13 and a Mac with the latest version of Catalina. Sidecar works just like any other secondary display that you use with your Mac. You can drag windows from your Mac to your ‌iPad‌, and vice versa. You can also interact with both devices using your Mac’s trackpad. It is a very useful feature, especially for artists and other users that require more screen.

However, Sidecar is far from being perfect. Since the feature has been launched not long ago, experiencing bugs and errors is common. For example, there have been several complaints about the “Device Timed Out” error in Sidecar that has been inconveniencing a lot of Mac users.

Once you’ve completed the steps above, you can then try reconnecting the devices via Bluetooth again.

Step #3: Switch to a Wired Connection.

If Bluetooth is really not working, your other option is to connect the devices using a cable. Make sure you are using an authentic charging cable from Apple because fake charging cables will just lead to more errors.
