Firstly, the Mac build is currently broken. I need to take a look into fixing that soon
But also, I should have put a warning out sooner for those out of the loop. MacOS 10.15 and higher have a Gatekeeper that doesn't allow unsigned apps to run easily on your computer. To sign an app, one has to pay Apple $100/year, which is a decision I really don't support. There are apparently workarounds to allow you to run unsigned apps. Here's one possible solution: https://www.imore.com/how-open-apps-anywhere-macos-catalina-and-mojaveBut again, Mac build broken for now.
