That's my last hope.
I recently downloaded KSP via steam for mac OS X. I am now sitting here already the whole day to fix that problem:
KSP simply doesn't want to start itself in the current version, instead every time it starts the v0.23.5.565 version of KSP which is pretty much unplayable in the career mode.
I just purchased it today and am completely helpless right now and can't solve this issue.
If there are any suggestions out there, pls contact me.
We discussed in a steam forum already about it and updated steam and reinstalled the game already. Still doesn't work.
