EDIT: Figured it out (sorta)
I'm not sure where the current queue is that will load when you boot up, but I found the next best thing:
Each savegame file includes its own modlist up at the top.
Your save game is here:
/Users/username/Library/Application Support/RimWorld/Saves/your_savegame.rws
The <modIds> tag, which should be near the top of the file, is followed by a list of all its loaded mods.
If you're using Steam I have no idea. I can't see one either.
If you have the DRM free version it's in your /SaveData/Config folder located inside the game folder.
Thanks, that was enough for me to go on! I've updated my first comment with the location.
Glad you found it! As you can see, the official forum tends to be best for technical questions =).

Well hot diggity. You made my day. I was looking for a quick way to get my modlist out of Steam. Thanks, man!
