Instructions on crash log

[cdspace]

I'm running on a macbook, with a few mods. And the game crashes, after spending an hour building a ship, trying to launch the ship, the game crashes. What data and logs do I need to find to submit to figure out why this happens?

Advance info: running on MacBook, KSP version 1.0.4, and a stack of mods. But running these mods in KSP 0.94 never crashed the game. I can provide a list of mods later, but right now, I've got SpaceY, BS9, SCANsat, the recent HabitatPack featured on the loader news, etc.

I'm just looking for where to submit a game crash log. I'm sick of this game crashing once an hour. This must be a bug. I build a ship, save it, come back an hour later and try to launch, and the game crashes ('Not Responding' in the Activity Monitor.)

And yes, I've reduced my graphics settings to crap, it still crashes.

What to do?
