OSX Yosemite does not shutdown - iTunes
I find that OSX Yosemite 10.10.1 Apple menu items do not respond after iTunes (126.96.36.199) has run continuously for 8 - 10 hours [Christmas music]. This office Mac mini (mid 2011) cannot be be shut down except by pressing power switch until Mac powers down.
While iTunes is running, other apps will run OK. Seems to be just a shutdown issue. OK after reboot.
Not sure if this is of concern, or just a nuisance. Ideas?
