How to use Apple Sidecar Wired Connection?

I want to use "only" the wired option, and with Big Sur and an M1 MacBook this has not proven possible - it wouldn't matter too much, but my network is slow, and sidecar produces a marked drop in download and upload speeds (I can't work out why that should happen, since surely the iPad and MacBook have plenty of bandwidth for "internal" communication), but using Duet, the problem is solved - no lag, no need for wifi on the iPad - just working as an extra monitor - so now I can uses ECAMM for live streaming with the MacBook screen, a second monitor and the iPad - so overcoming the limitation of only 2 screens with an M1 mac.

Hi guys! Also had this problem but figured it out. I'm on Mac OS 11.3.1 and iPad OS 14.4.2 Here are the steps I followed:

1. connect iPad to Mac with cable
2. open Finder on Mac
3. click on iPad in finder sidebar (it will be listed under Locations)
4. click on "Trust" on Mac
5. click on "Trust" on iPad
6. open sidecar on Mac, select iPad, and connect

You can test if your wired connection is working by turning off Bluetooth on the iPad. If there is no "trust" option on your mac, on your iPad, go to General>Reset>Reset Location & Privacy. Then, just disconnect and reconnect your ipad and start from step 3. Hope this helps!

Use your iPad as a second display for your Mac with Sidecar – Apple Support

Have you checked both devices are compatible?

Have you tried doing it without the cable?

Maybe they have removed the wired option with iOS 14/Big Sur.

I use sidecar daily and find it really good without a cable, no lag, no issues.

Thats using an iPad Air on iOS 13 and a MacBook 2020 on Catalina

I would suggest contacting Apple Support

It would be helpful, especially for others having similar issues, to share what you did to «solve the problem on [your] own...»

HoW? I would like my wired connect to work, regardless of Sidecar!

And how exactly did you do that?
