shutdown takes about 5 to 7 minutes. Screen goes dark, computer does not respond, but shutdown takes 5 to 7 minutes. In the system-log, no problems are reported.
I closed down all software running prior to shutdown (clamx-av, dropbox, owncloud), but no difference.

MySql oh my god!
Nailed it. Good call.
One note is the painful slowness of waiting for it to stop in the systems preferences is to kill it in terminal:
sudo /usr/local/mysql/support-files/mysql.server stop
Then disable it from starting on startup.
For those that traced this to MySQL (MariaDB in my case), what fixed it for me was changing the LaunchOnlyOnce value to true in /Library/LaunchDaemons/your-database.plist.
I have MySQL/MariaDB installed via MacPorts so I'm not sure if your mileage will vary if you've installed it another way.
What is safe mode?
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks, and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
Verifies your startup disk, and attempts to repair directory issues if needed
Loads only required kernel extensions
Prevents Startup Items and Login Items from opening automatically
Disables user-installed fonts
Deletes font caches, Kernel cache and other system cache files
Together, these changes can help resolve or isolate issues related to your startup disk.
Sorry, but no, no and no.
I've already tried your tips before writing here. Free disk-space is more than sufficient, caches have been rebuilt by starting in safe mode.
My log-in-items are tested (and cleared from garbage).
No way.
Shutdown takes 5 to 7 minutes, sometimes indicating that "kauth ... has timed out", sometimes staying in a state with spinning dented-wheel on a black screen.
But thank you for your ideas.
issue seems to be solved: I cleaned up the font- and user-related caches with a tool I greatly appreciate.
Now shutdown is faster than ever...
What tool? Lots of us are having this issue.
THe tool worked fine, the issue seemed to have gone. Two days later, it was back. This time, the tool couldn't
do anything to resolve the problem. :-((
Elsewhere, I read about an issue with the mysqld-daemon with macOS Sierra.
Having installed MySQL, I investigated the daemon and its behaviour.
And indeed, the daemon blocks on shutdown. It takes several minutes of patience, beach-ball spinning, when you try to stop mysqld.
After stopping it, shutdown is quick and with no hassle.
Seems, this is the real problem.
I was having the same issue. I did try all of the suggestions mentioned above. None of it worked.
After going through some forums, I found that the delay in shutdown was caused by MySQL service. Just uncheck the "Automatically Start MySQL Server on Startup" option and stop the MySQL Server (It took about 10 mins. Be patient). After that the everything is back to normal. No delays in shutdown or restart.🙂
I had exactly the same problem. From other forums it was suggested to turn off the Mysql Deamon. It should be possible to achieve this by going to System preferences and locate the Mysql icon. Click here and untick box (for auto startup). Shutdown your Mac. (Okay - I know it will still take a while !).
Restart Mac and hold down CMD+Alt (option)+p+r to reset PRAM.
Next time you shutdown - hopefully your problem will be fixed.
Thanks for this. Between the incessant issues with Time Machine unable to back up (having to hard eject my external drive almost daily time) and now having to (in this case) force quit MySQL and disable off auto start, I'm about fed up with this fast-becoming brick of a desktop. Macs used to be so reliable. Not these days. Sigh... </rant>
IMac 21.5" late 2013. OS X 10.12.1
Perfect! Solved my problem with the slow shutdown. Thanks!
Thanks..Problem is mySql..thank lot..🙂
after upgrade to sierra, shutdown is extremely slow
