Help! I am using Singularity on a MacBook Pro (mid 2010) with Sierra. For some reason the "Sit" choice on animations/scipts is greyed out and not able to be choosen as on Lucky Chairs, Transporters, animated furniture, etc. I have tried Firestorm and it is having the same problem. I would rather use it as Singularity does not support Bento, but Firestorm is much to slow on busy sims.
