Just wanted to post a follow up on the status of the 0.16 release:
We’ve found and fixed a few issues with the Mac version of the game, which apparently slipped past us during experimentals. We’re now in the process of uploading new game packages, which will be available at the KSP Store as a full download.
We are not going to use the old Patch System anymore. We have a new, completely overhauled update tool which is almost ready to go, which is able to patch and repair installations and is much more secure and reliable than the old version. We figured there is no point in trying to fix the old Mac patcher now, given that it is soon to become obsolete.
So, things should resume normality soon now. Again, we thank you for your patience and undestanding.
The KSP Dev Team.
