no-clue

I had it stuck on "Loading asset bundle definitions". Problem appears to be that I was running it from within my son's standard account which didn't have write privileges to the iMac's general Application folder and KSP got stuck attempting to write stuff into its KSP_osx folder within the Applications folder on startup. It worked correctly running it from an admin account. Solution was to take a copy of the KSP_osx folder and put it within my son's folder within the overall Users where he had full write access - worked immediately. (To do this, open Finder from the user account you want to get KSP working for, click on Go on the menu at the top of the screen; click on "Go to folder..." in the drop down menu; delete whatever is in text entry bar and type in /Users; click into the user you want to get KSP working for; leave that window open. Press command-N to open new finder window; click "Applications"; hold down the 'option' button and drag the KSP_osx folder from the applications window into the user's window to create a copy of the folder. Now run KSP from the new copy you've just made. You could just try copying the KSP_osx folder from Applications to that users desktop and run it from there; but if you are using iCloud for files, the desktop is in iCloud and you may have other write access issues - don't know, didn't try this).
