Building for Mac on PC

I have built my game on Windows, however when I am having issues getting it to build on Mac.

I have Mac support selected within the Unity hub and have set the Target Platform to be Mac OS X on the Build Setting menu.

When I try to just move the project folder from windows to mac and run it in Unity on mac, I get a ton of Errors: https://media.discordapp.net/attachments/675415186190106648/738417831275790396/screen_shot_2020-07-30_at_11.png

I am having to play telephone with somebody who actually has a mac and have built it and sent the file over. They are are saying that “it is .app but it can’t be opened”, and I do not know what to do from this point. Any advice?

Maybe post this on one of the platform forums.
