whenever I use the B9 aerospace-mod, the game crash. I use a mac, and it barely crashes when I don´t use mods. can anyone help me please?

I tried to start a new sandbox game, and this time all the parts appeared. unfortunately, something weird happened to the colors, and the game started to lag. Anyway, thanks for your help!!

I have tried to download and install the B9 aerospace several times, but every time, most of the parts are missing. What am I doing wrong? BTW, I use a mac.
