The gist: You have to run the game in Windowed mode the first time and change the resolution from the default 900x600. Play normal afterwards in full screen mode.
- Install Steam into its own bottle
- Install Tiberium Wars and or Kane's Wrath from within Steam as you would on a Windows machine
- Right click the game entry in Steam/Library
- Select Properties... General... Launch options
- Under 'Advanced users may choose modifications to their launch options' enter
-win
This will force the game to start in a window.
- Launch the game, and go to Settings/Graphics and select pretty much ANY resolution other than the 900 x 600 it defaults to. Optionally, set al the other graphics settings to high/ultra/etc if you want, but you can always set these later. It's changing the resolution away from the 900 x 600 that is key.
- Exit the game, go back to the Steam library and delete the '-win'
- Launch an enjoy - it will start in Fullscreen mode with your deleted graphics settings
Now, CrossOver will still give you some error after you exit the game, but that does not affect the game.
PS 1920 x 1280 with all other graphics settings set to max works fine on an M2 MacBook Air, but does slow down if there's tons of action.
Всем спасибо за внимание!
