It makes me wonder about the developers commitment for the future. I’m just not eager to invest (time and money) in an app that at this moment does not provide a universal binary and does not communicate on why it’s not available. It’s my understanding that Rosetta2 is not needed anymore after the application is translated, the only difference is that the binary is a bit less optimized for apple silicon than a universal binary would be. The first time you start an application directly after installing it might have some delay because the binary needs to be translated first. I have some apps that need Rosetta2 and in most cases I have not noticed issues with performance. I agree that it probably works fine and performance I also fine on apple silicon Macs. The app is going to work fine and you aren’t going to notice any performance issues. In my opinion, rejecting an app because it isn’t native-Apple Silicon is ridiculous.
