Since the last update to 10.12.1 my iMac locks up with the spinning wheel when I try to logout or change user. Sometimes it works but 9/10 a hard boot is the only solution.
It is most prevalent, but not 100%, when I've used iTunes which I know has had stability issues recently. However because it is not every time I'm thinking that might be a red herring.
