OS 10.10.5 never shuts down or restarts properly

[InquiringMac]

Every time I need to restart or shut down my Mac I have to press power button and hold it for a few seconds: it never works after just selecting and executing the appropriate command from Apple menu.


What is the cause for such behaviour and how to fix it, please?

avira, whatever that is, certainly seems to be all over the place.
When I run into shutdown or startup problems, it's usually because I've installed some weird piece of software that it turns out I can live without quite easily.

Thank you kindly!

Avira AV seems to be a respected product: please see here and there...
Do you believe it can be the cause of my problems?

First, can you log out of your user, then try to do a restart or shutdown while you are at the login screen?

When you get ready to shutdown, try a Force Quit (Option-Command-Esc). If you have already quit all open applications, there should be nothing on the Force Quit screen, except Finder.
If that is true, Force Quit the Finder, too. It will relaunch, and that's OK.
Close the Force Quit window, then try a normal shutdown.
Did that help you get a full shutdown?
Wait for the shutdown to happen, be patient for a bit, 5 minutes should be long enough to call it "not working yet"

Try uninstalling Avira.

I have seen a refusal to shutdown. Here's what helps me: Reinstall Yosemite.

Download the current Yosemite installer through the App Store. It will automatically launch when the download completes, so Quit the installer for now.
Make a USB bootable installer from that Yosemite app that you just downloaded. Instructions are available to do that. Or, download and run the good DiskMakerX utility, which is quite good at making a bootable installer that you can keep. You'll need an 8GB USB stick for that.
Boot to that installer.
Reinstall OS X. (You won't lose any of your files and apps, it just reinstalls the system, along with making sure that the system that you have is still properly installed.)
I think it will help you, as it did for me.

Uninstall Avira to see if it helps, which I suspect it will. Make sure to reboot. Once that is done, suggest that you also try Repair Permissions from Disk Utility.

Antivirus software by its very nature tends to sink its claws deep into the OS. This can cause problems when the OS is updated, changed out from under the antivirus. Unless both are kept well up to date, or at least version matched, trouble is nearly inevitable.
Is your copy of Avira up to date? Which OS version is it rated for?

Does the computer shutdown when running the shutdown command in terminal?

sudo shutdown -s now
