Just checked. Still needs it. I don't have Rosetta installed and I don't want to install Rosetta just to be able to use a game controller with DuckStation or Aethersx2. When I can also connect a PS4 controller and not need any of that.
replyYou have an old Steam.app stub, download the latest one and rosetta will not be necessary.
replyIf you had rosetta it would be able to self-update to the new universal binary, without it you have to do this one update manually.
I downloaded from here and I instantly get a pop-up about requiring Rosetta.
replyOdd if true. It's clearly a universal binary, not sure what's going wrong for you.
reply$ file steam_osx
steam_osx: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]
steam_osx (for architecture x86_64): Mach-O 64-bit executable x86_64
steam_osx (for architecture arm64): Mach-O 64-bit executable arm64
This appears to only be in the Steam beta - the version available for download still requires Rosetta. There doesn't seem to be a direct download for the beta - you have to opt into it after installing Steam.
replyNot the OP, but I just downloaded the latest stub from an M2 MacBook Air using Safari and it appears to be an x86_64-only binary:
