Yes. Periodically although everything appears normal suddenly the printer driver advises that is waiting for the printer and on separate occasions AirDrop advises that its is waiting. Both are resolved by restarting the Mac.
Personally, I think OS quality took a step backwards when Apple committed to the annual cycle of updates. It was driven, I believe, by the need to churn out new iPhones annually. If so, I think the marketing case for doing this could be somewhat weaker by now - but whether they will dare step off the treadmill, I very much doubt.
