Black Mesa on OSX doesnt launch

Hi, I have an iMac late 2012, intel core i7 3.4ghz, 16gb RAM, 1TB HD, GTX680 2GB VRAM…

I installed steam via winebottler and it works fine! I also installed black mesa with wine in the correct directory, it shows up in the menu and when I launched it for the first time it downloaded the source 2007 SDK…

but now that this has downloaded i wanted to launch it and it always shows me the same error:

hope you can help me!

thank you and enjoy your holidays!

sounds like the content servers unavailable bug mentioned elsewhere, I don’t think it was resolved but you can always install Windows
