Ok, after like two days I FINALLY got KSP again. I let KSP load in the background and stumbled upon some threads that said that the MacOS Sierra screws up unity. I went ehhh, maybe its just SOME people have this problem? So I wait a while (a hour) and nothing.
*deep breath*
So KSP doesn't work AT ALL on Sierra?!?! Please, please, PLEASE tell me this is only the case with 1.2, PLEASE!
ANY workarounds? ANY AT ALL?
Even if I have gotten the demo last week it STILL wouldn't of worked...
*sigh*
