So i downloaded Portal: First Slice the demo and tried playing it and the screen was kinda flashing and the little sign in the bottom right hand corner saying talk to the steam community press Shift+tab thing was flashing too. I could hear the sounds and if i clicked i the right spot i could play but not see a thing. The screen kept flashing. If you could help that would be awesome.
P.S. i did this on my Macbook and it said it was apple capable and it never told me i could play because of system requirements either. :flame:
