How to "undo" everything and go back to the backup?

[newoldschool]

Hello, newbie here. Before applying this patch I would like to know how are the steps to apply the SidecarCore backup file to go back to normal. I just copy/paste and replace it? Just that? and after restart it would be like if a never applied this patch on my macbook?

If someone is kind enough to list some steps, even if you think that those are obvious steps. Please help newbie community xD

Thanks!

(Also, sorry for my english, not a native english speaker)

Follow! I have a little problem here: after patching, my Macbook (air 2017) sees the iPad (Air 2) and there are the Sidecar icon and preferences but when I try to connect them I recive "Undefined error (32002)" and the iPad display goes black (not turned off).

Some people say that a repatch can fix the problem, so I've tried to replace the original file, but just can't copy and paste the SidecarCore back (yeah newbie here too)

Thank you so much for the guide @pookjw :)

I still have a problem, hope you can help me: I have disabled "system integrity protection" and I can run your patch. It didn't work completly so I tried to repatch. The problem is that I can't replace the patched file with the original one. (Hope that the images can help)

Finder doesn’t support copying to system. You should use this command.

sudo cp /path/to/original/SidecarCore /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore
