On the surface, TF2 seems to launch fine, except when it opens, the Valve splash screen is only 1/4 visible, down in the lower right corner of my screen.
When it gets to the loading screen, it's perfect, centered, but by the time it hits the main menu, it's back down in the bottom right. That means I can only see roughly the first half of the menu, and I can't figure out how to change resolutions, go to windowed mode, etc...
I have a new iMac 24", and yes, I saw other posts on this forum about some issues with the new hardware...so maybe I am out of luck, but I hope someone can help me
I have seen some people suggest running it with certain parameters (such as -windowed), but I can figure out how to apply those parameters.
