Okay, I'm probably repeating thread topics here but I haven't found an answer that will help me yet so I thought I'd post it myself.
I open steam up, that's fine. Slow, but it works fine, then I click on Left 4 Dead Demo and launch it. Then it says this:
I downloaded Directx 9.0 at the advice of my friend but I don't know where to put the .exe file when I'm installing it so I'm probably doing it wrong and when I open L4D, I still get that message, then it opens, isn't full screen and there's no menu.
Portal on the other hand does open but it freezes in like the first 30 seconds.
Anyways, I guess I'm asking if anyone can walk me through how to install a new driver so that my games will work and/or what else is wrong with them because a friend of mine, who has the same model Mac as me, same everything can run it and I can't.
I have a 15.4 in. Macbook Pro
2.2GHz Intel Core 2 Duo
Unfortunately I'm not extremely computer savvy and my friend who is knows nothing about macs so any help would be much appreciated :)
