Terraria not shutting down properly on Mac

[Kisha]

I recently upgraded to El Capitan, ever since I did Terraria and Trove do not shut down properly. These programs stay open in the background and when I try to play the game again later steam will not open them, saying they are open already. So I try to force quit them. That doesn't work. I then try to restart my computer, except nothing happens. I get the screens that say are you sure and all that. I even press the restart button, to make it go faster. However my computer does not restart. It stays on. After waiting for a while for this to see if it is just lagging, and having nothing happen I have to hard shutdown. By this I mean pressing and holding the power button. This isn't good for my computer, and I am going on about 2 weeks of this. Can someone help me figure out what is going on so that I can exit Terraria and play the game as intended once again?

Update: So it turns out that my wacom tablet software was causing issues with the programs shutdown scripts. What you have to do is go into System Preferences>Users&Groups>Login Items and check to see if you have any wacom software in the startup items. Remove this item from the list of startup items and then restart one more time. My computer now restarts properly and it shuts down games properly. Hope this helps someone else, because this is a frustrating bug with the El Caiptan OSX update.
