Help with installation

[A Random Kerbonaut]

So I was downloading Luna multiplayer mod on Mac, and it asks me to take a game data folder and put it into the KSP folder. When I do that, it asks me if I want to replace the file. I tried renaming the file but it doesn't work.

The Luna Multiplayer mod likely came pre-packaged with some or all of its dependencies. Module mMnager is an example of a mod that a lot of other mods require, and mod makers are generally allowed to include Module Manager in their files.

If you open your gamedata folder inside your KSP folder and the one in the mod download folder you'll likely see a few folders and perhaps a few .dll files. Your system is likely warning you about overwriting these when it gave you that error. Simply move over the individual files and folders from the downloaded gamedata folder to your ksp/gamedata folder that arent already there.
