Portal 2 won't inicialize
I just bought Portal 2 last night as part of the Steam Summer Sales and was really excited to start playing. After it finished downloading, I clicked "Play" and the thing would pop up like it would for any game but then it disappeared. I had this exact same problem with Left 4 Dead about a month ago, and in that case it was due to a bad update which Steam later resolved. Was Portal 2 updated recently? because that might be it. Also, I'm running Portal 2 on Mac OSX Snow Leopard (10.6.8). When I had this problem with Left 4 Dead several people commented saying they had they same problem and they where Mac users as well, specifically 10.6.8. Is anyone else having this problem? Any responses would be much appreciated.

I am having this same problem. I can't find a fix either.

EDIT:
I have now noticed that NONE of my steam games seem to be working. Some of them come up with error messages and some just disappear.One error message i got was "SteamStartup() failed: SteamAPI_Init_Internal failed." Another one was "Failed to locate a running instance of Steam." I also got "Steam Error: No SteamUser. -Make sure that steam is up to date -try restarting your PC - try Garry's Mod -> Delete Local Content. Please let me know if you solve this bug!" {Please note anything in quotes is from an error message}
Any help would be much appreciated!

I already submitted a ticket to Steam. I suggest that you do the same as well as anyone else who is experiencing this problem.

I found a fix guys! (I think...) What i did was uninstall then reinstall the game and restart my computer, then... Poof! Everything was all hunky dory in the land of Gaming! You should try it!

Hello! My computer is also a Mac 10.6.8. I've been having the exact same problem with Portal 2 where I'll click the game to lauch it, a little window will appear telling me the game is lauching, and than nothing happens. All of my other games work, it's just Portal 2. I've tried uninstalling and reinstalling, restarting, and verifing the caches, but none of those fixed any of the problems. From what I've been reading on the other forums, apparently this is an issue a lot of mac users have been having, and I think it is connected to a recent update of Portal 2, but I am not entirely sure. It sounds a lot similar to the Left 4 Dead issue you were having tho, and I was wondering if you could tell me how long it took Valve to solve that issue?

Hello! When I had the issue with Left 4 Dead, Valve responded after a couple of days. Although, when I posted a discussion on it a lot more people responded with the same issue, so that might have played a roll in it. I already submitted a ticket and now I'm waiting to see what happens.
