Counter-Strike: Global Offensive is a hugely popular game with more than 10 million active players. Given the size of its community, it’s inevitable that some of those who play this first-person shooter will be using a Mac instead of a PC. But such users can sometimes experience a bug that the CS:GO won’t go fullscreen on Mac.
On a PC, CS:GO uses the full-screen mode by default. When you first enter the game, you will immediately realize that the display mode is full-screen. And if you like it that way, you don’t need to do anything about it. If you want to exit full-screen mode temporarily, you can do it using Alt-Tab.
If you want to exit full-screen permanently and play using the windowed mode. You can go to Settings and select the windowed display mode. But if your game is windowed by default, what do you do?
The Problem on a Mac
The main problem with trying to change to full-screen on a Mac when the game is in the Windowed mode by default is that you often don’t have the possibility to do so from the game settings. Normally, you would go to Settings, Video, and then find the Display Mode option. From there, you can select whatever option you prefer.
But if going to settings and changing things from there is not the answer because it’s not available to you in the video settings. You will need to take a different approach.
The solution to this bug that sometimes appears when playing CS:GO on Mac computers is to use the command line in Steam.
Just open your Steam Library, right-click on Counter-Strike: Global Offensive, select Properties, click on Set Launch Options in the GENERAL tab, and then type -fullscreen. Click OK, and everything should work now the way you wanted to. Your game should open in Fullscreen mode and allow you to play CS as everyone else does.
Although you haven’t been able to properly use your display settings from inside the game. The problem will be fixed, and everything else should be working properly. The rest of the video options will be available to you. So you can change your in-game resolution and all the other settings that control the quality of your visual experience.
Playing CS:GO on Mac computers can be annoying from time to time because the game was primarily designed for PC users. But that doesn’t mean you can’t find workarounds for the various bugs that may trouble you.
