Black Screen on Store!

I'm running steam on my MacBook Air, and it's worked fine up until a few days ago. Now, when I try to access the store, steam workshop, community, or any other online features, I just get a black screen. I have internet access; in my games library, it still loads recommended mods. This is a real pain in the but, and I have reinstalled steam and refreshed steam files, but I still get the same result. Any suggestions?

I have the same issue! its starting to really bug me because i want to trade already!!! i went to use the online site and i have to wait 7 days now because its a "New Device" AHhhhhhhh

Same thing happens to me.. The only thing that works (I think) until a fix comes is going in "Big Picture Mode" (The console next to your name in the upper right corner)

MacBook Air - It's not a MacBook update which makes Steam load wrong, cause I haven't updated my Mac for a very long time

Macbook Pro ultimo 2011, Mavericks

There appears to be a problem in how Steam on Yosemite is linking up with embedded Chrome. There's a command you can run from the terminal to collect an error message; details in this thread: http://steamcommunity.com/discussions/forum/2/618457398972146649/. Paste your results there, hopefully can get a fix if enough people post.

The errors logged is:

Do you use Yosemite? Because there are a ton of people saying they're having the same problem with the new update on it.

Someone knows the solution?

Black Screen for Steam App

Hi,

I have a problem. Whenever I use Steam downloadable app OR steam overlay, I get a black screen. It is like this for everything but library. Is there any way to fix this or is the deleting and uninstalling Steam the only way? I have an IMac. I have no gotten Yosemite yet.
This is also affecting my achievements, I am not able to get any.

I am getting this in my terminal, it no longer lets me write a single letter/symbol without saying error buffer error:
