L4D2 BLUE TINT SCREEN PROBLEM

[Yogi]

Hi, I have got this problem when I enter L4D2 my screen will immediately has a blue overlay.... Can someone tell me how to fix it? I own a 13" MacBook Air and my friend who share the same computer as me does not have this blue overlay when she play it.

Hello and welcome.

-I assume you mean Left 4 Dead 2 on Steam?
-Which exact model is you MacBook Air and your friend's?
-Which version of OS X on them?
-Which version of the Steam app on each?
-Are you both running the same Steam and game settings?

hi..

yes l4d2 on steam.
it is A1466 same version
Mine is Sierra, friend's Yosemite

The rest i'm not sure... does the game settings affect?

Maybe it has to do with under the hood changes in Sierra over Yosemite.

You could try the Steam Discussions for further troubleshooting, as I do not have any experience with Steam. There may be someone there with a similar issue.
