The app for mac is now fixed and re-uploaded - it was related to code signing. Thanks again for reporting this issue!
Still not working :(I download the fixed version already.
Sorry for that. Seems that macOS doesn’t like to run unsigned applications. But there is a workaround:
If you see “damaged and can’t be opened”, open Terminal and run: xattr -cr “/path/to/Tile Map Alchemist.app” Then try opening the app again.
It's working! Thank you.
