OSX 10.8.2 Upgrade on Mac Pro (4,1) Sleep issue

Question

After updating my Mac Pro (4,1) to OSX 10.8.2, computer goes to sleep too soon even when Computer sleep in Preference's Energy Saver is set to "Never." I can have the DVD player open and playing a movie, then the computer won't sleep, but if I stop the player, the computer will go to sleep after a couple of minutes regardless of where the Computer sleep pointer is set in Preference's Energy Saver.

Answer 1

hmm....!!! My Mac Pro (4.1) 10.8.2 computer have the exactly oposite problem.
It do not go automatically to sleep (system preferences / Energy Saver Settings).
Only the display go to sleep. Mac stays awake.
When I press the power button on my mac pro it go to sleep, though
(Or if I use the apple menu and manually make my mac sleep).
Here is my situation.
a) Before Mountain lion I had my mac "never sleep" (in system preferences / Energy Saver).
b) After Mac OS X Mountain Lion 10.8.2 I decided that I wanted to set my computer to sleep after 15 minutes of inactivity and leave it open all day.
c) I Configured the System Preferences / Energy Saver to sleep after 15 minutes.
The computer closes the display but not the mac (mac don't go to sleep).
If I manually put my mac to sleep (hardware button or mac os x menus), it goes to sleep.
The workflow I followed was the below (did not succeed until now).
1) Repaired Permissions with Disk Utility.
2) Cleared ACL's with BatChmod on my users/myhomefolder.
3) Did a system cleanup with Onyx.
4) Reseted NVRAM / PRAM --> http://support.apple.com/kb/ht1379
5) Reseted the System Management Controller (SMC)  --> http://support.apple.com/kb/ht3964
6) Booted in Safe Mode and try the automatic sleep there --> http://support.apple.com/kb/HT1455
7)Checked for unfinished "printing jobs" (queue) in system preferences / printers.
8) Booted on a clean install of mac os x mountain lion that I had on an external drive and try to see if my mac goes to sleep.
9) Turned off any "Sharing" I had on in system preferences (I had on the File Sharing and the Screen Sharing because I Use iTeleport a lot).
10) I Killed any application that might block the mac from go to sleep (i.e. Dropbox (lan sync = off), VLC Streamer, iTeleport, Boxcryptor).
11) I Created a new account, then logged out from my account and logged into the new account (so that no "keep awake the mac" programs load at startup.
12) I used the console and the command "pmset -g assertions" at some steps to check if something was wrong there (and by eliminating all the possible "suspect" elements I had finaly my system reporting the following
Here is the command that you should execute on terminal.

I unmounted and disconected the Firewire 400 and firewire 800 external HDD (that should not be a problem normally because I like to have them mounted and connected to my system all the time and the system should be able to go to sleep)

So, the conclusion is that
a) I don't know If the problem exist before 10.8.2 update.
b) My Mac Pro 4.1 goes to sleep when I make it to sleep (by pressing once the hardware power button of my mac or by clicking with the mouse "apple menu/sleep")
c) My mac does not go to sleep automatically through the "System Preferences/Energy Saver" even when I set it to go to sleep after one minute. (only the display go to sleep, not the mac).
d) In the system Information (about this mac) under the "power" menu I got
System Power Settings:
  AC Power:
  System Sleep Timer (Minutes):          1
  Disk Sleep Timer (Minutes):          10
  Display Sleep Timer (Minutes):          1
  Sleep on Power Button:          Yes
  Automatic Restart on Power Loss:          No
  Wake on LAN:          No
  Current Power Source:          Yes
  PrioritizeNetworkReachabilityOverSleep:          0
Hardware Configuration:
  UPS Installed:          No
The fact that I see those settings here too, leads to the conclusion that the "new settings" that I configured in the "System Preferences/Energy Saver" earlier, are "saved" correctly.
e) Even in "Safe Mode", the mac do not go to sleep automatically (only manually).
So can anyone help? What could be wrong and my mac do not sleep automatically in Mountain Lion 10.8.2 ?
