The same way you take screenshots in macOS. Shift + Command + 3 or Shift + Command + 4. The game and Crossover still run through macOS so macOS commands apply to all apps.

Thanks, but that just saves a screenshot to my Mac. When running the Mac version of Steam, I can take screenshots that save to my Steam Post Game Summary. I’d like to be able to do that through the Crossover PC version of Steam on my Mac.

I’m finding out that the issue may be that Steam Overlay doesn’t work with Crossover yet?

I see, I haven't taken screenshots with Steam so that may be true.

Did some research, Steam Overlay doesn’t work with D3D in Crossover. Need to use DXVK… but that gives problems with the games.

Could potentially solve this with a work around that launches Windows games directly from the Mac Steam client… but it’s quite technical: https://github.com/natbro/kaon

Don’t think it’s something CodeWeavers has plans to fix anytime soon.
