Google-Chinese-Results-Blocklist VS free-sidecar

Not sure which macOS version you’re running but you can try your luck with Free Sidecar. It enables unsupported Macs and iPads to also use Sidecar. It’s worked for me in the past, problem was I was trying to enable support on an iPad Air 2 and Sidecar only works with an Apple Pencil (IPA2 does not support Pencil) so it did not work regardless. But it may be able to help your situation.

My Macbook meets all of the requirements to run Sidecar and Universal Control perfectly fine, but my iPad is just one generation too old. I feel like it should still be capable of supporting Sidecar since I've already found what looks to be a working method to run Sidecar on much older Macs and iPads ("Free Sidecar" https://github.com/ben-z/free-sidecar). This method would not work for me though, I believe because my Macbook is updated to Monterey and this was designed a while ago for Catalina. If my iPad can go as far as running Universal Control, that would be even better.

Also, when following this guide found in a different post (https://github.com/ben-z/free-sidecar), I try the first step to make a backup file for Sidecar, by running this in Terminal: cp /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore ~/Downloads/SidecarCore.bak

I'll leave this here https://github.com/ben-z/free-sidecar, you can always try it before upgrading to a better iPad.

-ben-z's free-sidecar ONLY IF your SMBIOS doesn't support Sidecar natively. I don't know for sure but if it can run Big Sur odds are it can run Sidecar. The method covered in this git readme might not work though if Big Sur changed codesigning.

Nice work, but check this out: https://github.com/ben-z/free-sidecar
