All tests run on an 8-year-old MacBook Air. All results from shipping 7 Mac apps as a solo developer. No sponsored opinion. Intel Mac users still exist. Apple Silicon is the future. A universal binary covers both with one DMG. Here's the actual process. Why bother with universal binary Rosetta 2 exists. Intel users can run Apple Silicon binaries with it. So why compile universal? Because "this app requires Rosetta" is a friction point at install time. Some users don't have it installed. Some corporate machines block it. Some users just don't know what it is. A universal binary runs natively on both architectures. No conversation about Rosetta. No support tickets. The Tauri build command bash rustup target add x86_64-apple-darwin rustup target add aarch64-apple-darwin npm run tauri build -- --target universal-apple-darwin That's it. Tauri handles the lipo step that combines both binaries. The output is a single .app that runs natively on Intel and Apple Silicon.…
