Hmm, can you share some details to figure that out? The build was tested by someone else with MAC too and ran without errors, it's true that you need to take a few steps because running an app from an unknown developer and so on, like here https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unknown-develope...
Besides that, I'm not really experienced with MAC but share the error through pastebin or something so I can take a look at it.
