Sidecar works but can't interact with screen on iPad

Hi, so I updated my MacBook Pro to Catalina and it works fine. I tried out sidecar with my iPad 11" Pro and it works, I can click on the modifier buttons on the side. I can't seem to be able to use my finger or Apple Pencil to interact with the mirrored screen however. Am I missing something? How can I get it to allow me to open applications, close, scroll etc. all from the iPad screen only?

iPad Pro 11-inch Wi-Fi, Cellular

Fix Found!


I found this posted in another thread with person with same problem. This worked for me and I hope it works for you! I will Copy and Paster for you......

Try the following on macOS Catalina:


  1. go to System Preferences
  2. klick on Security (house with safe-icon) then on the Firewall tab
  3. klick on the lock at the lower left corner and enter your password
  4. klick on Firewall-Options
  5. uncheck “block all incoming connections” (or something similar – depending on your language settings) on the very top of the window
  6. restart sidecar


For me this setting solved the issue with the not working apple pencil together with sidecar.
