Version: 0.25.0.642 Steam OS: OSX Yosemite 10.10 Screenshot: http://gyazo.com/a38530eb5ad9958d3c586deebb401615 I've downloaded the latest KSP from Steam onto my mac running Yosemite. I can't seem to click any menu items at all. I can click the diagnostic menu when it first opens, but not any of the buttons. Any ideas?
