try this i copy from nother site from Interactive Civilian so this not from me just posted to help you out to get game working hope it works out for you


A lot of people are having difficulty getting it to launch (I just switched over to Mac OS to make sure everything was good and had the same difficulty). If you go straight into it from pre-loading -> decrypting -> downloading the little update -> launching, the game will most likely crash on launch before getting to the game menu.

Simple solution: right click on Portal 2 in your games list, select properties, go to the Local Files tab, and click the "Verify Integrity of the Game Cache..." button. It will re-verify your files, and you'll get yet another download (mine was about 11.5MB) as it downloads the missing or corrupted files.

After that, everything should be good. Fair warning: Performance on Mac seems to be much lower than on Windows, so if you've got a Windows/Bootcamp partition, you'll probably have a better experience playing on that. I'm basing this on the huge difference in what the game chose as default video settings, and one of the developers on the Steam forums stated that they'd done their best to optimize how the game chooses the best settings.

Anyway, hope this helps anyone who's been frustrated by this.

Thanks for posting a screenshot, after looking it up quickly I have found this post from Valve:

That confirms that the X1600 is not supported, unfortunately you will not be able to play Portal 2 on that computer.
