Transfering KSP from Windows 10 to Macbook

[CreativeKid12]

I originally got KSP on my Windows computer (not with steam), and I just bought a brand new MacBook Pro. I would like to know if there is a way to transfer KSP from my windows computer to my MacBook Pro.

Transfer the game?  No.  But you can transfer the mods/save files.

Do a fresh install of the Mac version.  You get the installer from the same place you got the Windows version.  You don't need to re-buy the game.  When you buy KSP, you get the Windows, Mac, and Linux versions all at once, regardless of where you get it from.

Once you have the fresh install on your Mac, copy the content of your saves folder from the Windows machine over

If you're running mod, copy the contents of your GameData folder over (minus the Squad folder).
