Same error for me too. They should not be selling a product that does not work for Mac users.

It has been working for me up until today. I last used it yesterday morning. This is pretty standard. Things work for a time, then the streaming services change a few things here and there which causes SF to not function properly. Updates fix it. A competitor of SF just pushed out an update for their product for Mac, and things are working fine there again. SF is snail slow with Mac updates lately, which is frustrating since, when it works, SF is the superior product in my opinion.
