Q: Mac Pro does not sleep
Hi
I noticed, that my Mac Pro (Late 2013) with El Capitan does not go to sleep anymore, neither automatically nor manually by using the Menu.
The Screen turns black, but it is still running. I tried the "pmset -g assertions" command in the terminal, but nothing is preventing the Mac from sleeping. Same with the Activity monitor in the Energy saver Tab. I also did a RMC and Pram Reset.
I think the last backup might be the Problem: I had a Macbook Pro, and i used the Backup from the Macbook, to restore the Mac Pro.
It's just a long shot, but i probably set the Sleep Setting to Never inside of the System Settings of the Macbook, and that setting is not available on the Mac Pro.
Is that causing the Problem? Or does anybody know another solution?
Thank you!
MacBook Pro, OS X El Capitan (10.11), null

Please test after taking each of the following steps that you haven’t already tried:
Step 1
Take all the applicable steps suggested in this support article, including the ones under the heading "If the previous steps don't work." That's the starting point for any further effort to solve the problem.
Note that, as stated in the article, the computer will not sleep if some sharing services are enabled. From the menu bar, select
▹ System Preferences... ▹ Sharing
Turn off all sharing services.
Also note that the "external devices" referred to in the article could include Bluetooth devices, other than those made by Apple. If you're using a MacBook, MacBook Air, or MacBook Pro, or if you're using a desktop Mac with a wired keyboard and mouse, turn Bluetooth off to test.
Step 2
If iTunes Music Sharing or Home Sharing is enabled, disable it or quit iTunes. Do the same with any third-party applications that have a similar feature.
Step 3
Select
▹ System Preferences... ▹ Accessibility ▹ Speakable Items: Off
Step 4
Select
▹ System Preferences... ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 5
Open the Printers & Scanners pane in System Preferences and select each printer, then click
Open Print Queue...
If the printer status is "Paused," click the Resume button in the queue inspector. If there are any unfinished jobs, either finish them or delete them.
If you can't clear out the print queue or get the printer out of "Paused" status, delete the queue and recreate it.
Step 6
Back up all data.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/var/vm
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.
A folder named "vm" should open. Inside it, there may be a file named "sleepimage". Move that file, and only that one, to the Trash, but don't empty yet. You'll be prompted for your password. Close the folder window.
Restart the computer and empty the Trash.
