It really has to be Wacom... did the same, delete it from the login in safe mode and now everything's fine....

How can a single program mess things up??

You must uninstall Wacom driver first:

and then uninstall Wacom apps.

Yes this is currently happening to me too. I tried to re-install, but still didn't work. I tried safe mode but still didn't work. Everything works out really well. Just the shutting down part from the apple logo, is just weird, it won't restart or shut down.

The apps at the dock is still active.

Any steps that I need to try?

Open SystemPreferences (in your Applications folder) then open Usrs&Groups, select the LoginItems tab:

in principle you do not need anything there. You remove the entries with the minus sign underneath.

In my macs I have Canon IJ in there only: this is the scanner driver for Canon printers/scanners/multifunctions, and I have those. This scanner is not easliy started by hand when needed. I don't have apps in the LoginItems, and just start all aaps by hand when needed.

After removing entries, do a restart of the mac.

I had the same issue. MacPro did not shut down, the empty Finder screen remains active but was impossible to do anything but a forced restart.

To solve I had to uninstall the Wacom drivers from the System Preference AND from the Login Elements.

Now the MacPro reboot or shut down as usual.

But I can't use the Wacom Bamboo tablet.

diegotrystero,

For me, after I completely removed the Wacom software and shutdown/restart worked, I was able to reinstall the Wacom software and everything was fine.

I have seen problems with their software in the past, following an OS X update. Never this problem, typically it has been display anomalies. But, every time, once it was removed and OS X working fine, I was able to reinstall the Wacom with no further issues.

You're right! thank you.

This morning I deleted ALL the Wacom items still in the OS Library and User Library.

Then I reinstalled the Pentablet_5.3.6-6 driver and now the Bamboo tablet works again.

Many thanks for the very helpful advice here. I had the same problem and following the steps outlined here it's now fixed. Wacom was the problem.

Exact same issue for me - Your "Bamboo Core" find was the key - found it active in my Activity Monitor, killed the process, and my Mac resumed shutting down immediately.

Thanks for the help, everyone!

Had the same ****** issue, I reseted the NVRAM, deleted some preference files, did almost everything I read on the web and came here, and in fact, it was an issue with my wacom driver, as soon as I uninstalled it, BAM!!! my mac could shut down with no problem at all! Thank you guys!! This was driving me NUTS!!! you just gotta delete your wacom drivers and that's all 😀

THANK YOU!! I did all of the Wacom Uninstalls - Pen Tablet, Bamboo etc... and this suggestion, to remove it from the Startup items (Somehow a remnant was still there) worked. I even downloaded the "EasyFind" app per a response here as well, but I think this final thing did the trick.

good work! be happy,

Same issues here using Mac Mini. Just resetting SMC returns to shutdown/restart.

Posting in case someone happens across your thread with this issue:

There may be several sources for this issue, which seems to always point to some background app or plugin that won't let the Finder quit. And many times, it seems that the program won't show up in monitors and logs that it's the offending source. I've had this problem for other a year, and every single suggestion regarding disk repair, resetting PRAM, reinstalling the OS, restoring from a backup, etc did not work at all. The issue will not show up in Safe Mode tho, suggesting that it is a file that runs once you log into your usual user or admin accounts.

In my case, I finally found a thread that suggested it may be an issue with Avid ProTools plugins. Going to /Library/Audio/Plug-ins/HAL and deleting Digidesign plugins (in my case, it was Digidesign_CoreAudio.plugin and DVCPROHDAudio.plugin) solved the issue after a hard restart. My MBP will now IMMEDIATELY go to a black screen on restart and shutdown. Log out also works every time.

Unfortunately, every thread I've come across will all suggest different files. Sound drivers, virus protection software, USB drivers for peripherals--they just won't play nicely with 10.11. If your particular case isn't a Wacom driver or Avid plugin, keep searching and hopefully someone will have a suggestion that leads you in the right direction.
