That's some good information for others! I hope this means other Mac users can continue to play the game. Thank you for writing the reply :)
It sadly didn't fix my problem completely, but it's a good idea, since it might limit further problem. Anyway, for anyone with the "private/var/folders..." error about "translocation" during the avatar creation on MAC, the way I fixed it was moving the game app itself out of the folder and into the "applications" folder, and then opening the game via Finder. It's apparently due to a security feature from Mac 10.12.
