I checked I have 117 GB of storage left, and 8GB of memory left.

Yes

I checked all my files, and I can't find one called KSP_x64

I am 99% sure I still have enough storage, the problem I think is that I'm still using the 32bit, and no one has still answered my question of how can I get my macbook to run 64bit.

Wait, I Have another problem. Now whenever it tries to load the game on 1,4,5, it just freezes right at the end of the loading sequence, so after the yellow bar, but before the main menu. I don't know what to do.

Thank you, I finally understand! Edit - NVM, read post below.

Thank you for say that, but I'm still confused on how moving the KSP folder to another location would help me with my mod problem.

First off, I am using a macbook Second off, Kopernicus is at 1.5.0-1 but kerbal star system is that 1.4.4. But when I tried switching versions to 1.4.4, it still didn't work, so I'm pretty sure it is the 64 bit thing. But the problem is, and I don't know why, but all the methods people say to make KSP run at 64 bit don't work for me.

Geonovast - Yes I do

Geonovast - The mods I'm trying to use are Kerbal Star System, and Kerbal Exo-planet. I've tried everything but they won't work. Also I think the problem is I need KSP in 64bit, but I can't get it to work, and I don't know why it isn't working for me Edit - I have installed module Manager

So, most mods work for me, like mods that add items or parts into the game, but for some reason, mods that add visual enhancement, or add planets or objects in space don't work for me, even though I follow and do what they say to do. Maybe I'm dumb, but if anyone could help me out, that would be great, since I wanna improve my games visual appeal, and add more planets n' stuff.
