I can't seem to find any official documentation. The wiki says to use the "patcher" (http://wiki.kerbalspaceprogram.com/wiki/Patcher) but the link for OS X ends up redirecting to the KSP home page. There's also a forum post that says the patcher doesn't work for version 1.0 I've tried using the "Launcher" application, which was suggested in another forum post. When I open the Launcher app it just says "Checking for Updates..." forever. I got 1.0 by downloading a brand new game from the main KSP website, but I don't wan to start the game over every time an update comes out. What am I missing? Side question: is there any official documentation? The support page on the main KSP website just has an email link.
