Glad to see Valve is putting so much effort into their macOS ports
Some context: .exe is the executable format for Windows. It's fine that Valve is using some translation layer instead of doing a port of Counter Strike 2. This error does however suggest that they don't even test their games before releasing them on macOS.
Yep I read this as well! It's weird they published the Windows build for macOS though. Usually games that are not available for the current platform, simply show up as "unavailable", CS2 was simply installable.
