Hey cool people!

I have a macbook air, and I have been running all of the elder scrolls and fallout games without issue. this one tho... geez.

Bought steam version, didn't work. Many suggested GOG version, so I came here. Crashes on New Game.
Since I am running a Mac, im having a hard time finding the compatibility change that seems to fix this. jaja everyone says, ¨Oh you just have to right click on fallout launcher, properties check the box. But the propertys option isn't available on a Mac.

Anyone have any idea how to make this happen? I really wanna dive back in. Boyfriend is outta town, so I have many days to play! Help! jaja
