@Nils277, I am running KSP on a mac without using steam and am having trouble getting the mod to show up. It shows that it is loading in parts on startup but the game is essentially running vanilla. I've tried putting the putting the contents of the GameData file (Kerbtrotter and localizer) in the normal one and a bunch of other methods. Am I doing something wrong, or is this not configured for mac? It may just be a matter of redirecting the localizer based on the mac names for file locations. The mod looks really cool, so I'm hoping I'm just doing something wrong and that it's not completely incompatible with mac. Also, is module manager needed to run with the planetary base mod? I haven't downloaded it yet just wondering in general.
