ℹDeleted Little Snitch! Basically its because of any of the program not functioning properly, In my case Little snitch got corrupted which was churning out this problem!! The moment I removed . Finder was back to normal and shutdown/restart issue vanished.🙂
Take backup. (although its not compulsory but take it for caution)
And then proceed to lastly if you are unable to find out that program then go to the recovery mode and run disk utility!
if no luck then go for fresh Os download in recovery.

El Capitan will not restart or shut down after I installed it on my MacBook Pro. It simply hangs up and does nothing and I have to manually shut down by holding the power button down.
