Sierra was giving me a hard time. Circular beach ball kept popping up, time machine didn't work, etc. I switched, this morning, from Chrome to Safari. So far everything is working as it should. I guess that 10.12.1, should fix everything.
I guess I have been fortunate. I have been running it since the developer beta was release and have had no issues. I use Firefox, not Safari. Well glad to hear it has settled down for you.

I also found Chrome was causing the "Wheel of Waiting" to spin causing frustration. Removed chrome and went back to safari as well.
