some time ago I ran into problem, sometimes when i try to shut down mac it won't shut down loading wheel is just spinning and I have to shut down with the button. I tried SMC and PRAM reset, the problem keeps occurring. I am guessing it's some kind of problem with the apps, because it happens EVERY time if i press ,,reopen apps'' at the shutdown pop-up (when it happens only sometimes without that box checked). How can I solve this problem?
P.S. I don't have Parallels installed, I know it sometimes causes the problem.
