The Mac app isn't notarized, so I had to bypass Gatekeeper on macOS Tahoe. It's also an Intel application, so it runs with Rosetta on my M4 Mac mini. If possible, please make this a universal binary in the next version, especially since Rosetta will be going away in the next few macOS releases.
The Mac app should be notarized as of the latest version, so that’s unfortunate you had to bypass Gatekeeper! What version did you run (graphical, command line, demo, etc.)? I’ll definitely look at making it a universal binary in the next version, not sure what’s involved in that yet for a MonoGame project. Thank you for the report, not that many Mac users, so this is definitely valuable info!
