Hey all, I hope this is the right forum for this. Somedays my grandparents make me feel like a computer guru and other days I forget where I put a downloaded file. I currently am running KSP off of my MacBook Air and I have had KSP original package downloaded for quite sometime. I originally downloaded it off of Steam I believe, but don't remember my Steam login info. I'm trying to get that figured out now.
I am running 1.4 version. I'm awful with understanding updates but apparently downloading the new ground breaking version of 1.7 2 won't work off my current version. So now I'm just wondering what do I have to do to update it. Thank you!
