MacOS Catalina: Sidecar not working with v9.1.3

[steve1607]

Hello guys,

first of all thanks for providing a compatible version for MacOS Catalina.

I have an issue in v9.1.3: I use Apple Sidecar to use my iPad as a second screen. This works fine without the VPN, but when I log into the VPN with Pulse Secure v9.1.3, the sidecar connection crashes and the Mac tells me, that no Airplay/Sidecar connection between the iPad and Mac could be established. This occurs also when I connect the iPad via USB to my Mac.

Am I missing any configuration or is this a known issue? Do you know any workaround?

Kind regards,

Steven

Is it something that was working with old version macOS and Pulse client combination?

Hi Steve, I just got a free MBP, could you please share me the client image I can use it to do a test.

It seems that AirDrop will not work when connected to VPN. Documented by Apple - Known issues in macOS Catalina.

Is that similar to Sidecar?

Sorry for the late reply. Yes, this seems to be the same issue. So this seems to be Apple's fault. 

For everyone else, who has this issue: You can use the app duet display. They support a wired connection via USB, which is not affected by the VPN.
