Mac app not working

[pixxelpusher]

I can't seem to run the Mac app on M1 Mac, OS 12.4. Get "The application “dithermark.app” can’t be opened." error when trying to run it.

Sorry for the late response. I have tried re-downloading the Mac app and you are correct it can't be opened. It seems if you compile the Mac app locally, you can run it, but when you upload it and download it again it doesn't work. I assume that would be fixed by signing up with the Apple developer program for $99 a year. However I don't want to do that, partly for financial reasons, but mostly for philosophical reasons, as I don't believe in requiring a subscription to develop software for an operating system.

In the meantime, if you want to run the Mac app yourself, you can follow the directions on the release on how to compile it from source.

Chiming in here @pixxelpusher. Two simple ways to run unsigned mac apps that on latest macOS.

1. Right-click on the .app and manually click "Open". macOS finds this more "intentful" and allows opening unsigned apps this way.
2. Otherwise, after macOS complains about the app being unsigned, Go to Settings > Security. You'll see an option to "Open anyway". Do it, say yes to the security prompts. You'll only have to do this once per app.
