Sorry guys, my stroke brain is a little confused.
What DJI Assistant do I download for my OG Goggles?
Do I also download the Assistant for the Mavic 2?

It isn't a case of stroke brain.  It is a case of confusion caused by DJI.  
Don't know about OG Googles.  But there is a version of Assistant-2 for Mavic Pro and different version of Assistant-2 for Mavi 2.  

Good luck getting Assistant-2 to work if you use Mac OS-X.   
Good luck getting Assistant-2 to work if you use Windows 10.  
Basically good luck getting Assistant-2 to work period.
