Q: Permissions problem in displaypolicyd

I'm having a very strange problem with Yosemite 10.10 (14A389) on my MacBook Pro (13-inch, Mid 2009). Waking from sleep the monitor receives no signal.

The only problems I have come across is a few permission errors:


User differs on “private/var/db/displaypolicyd”; should be 0; user is 244.

Group differs on “private/var/db/displaypolicyd”; should be 0; group is 244.

 

sudo chown -R root /private/var/db/displaypolicyd && sudo chgrp -R wheel /private/var/db/displaypolicyd

or

sudo diskutil repairPermissions /

 

After repairing permissions problem reappears after a reboot.

MacBook Pro (13-inch Mid 2009), OS X Yosemite (10.10)

    I have the same permissions issue with a MacBook Pro (15-inch, Early 2011) where these following permission problems keep returning after reboot.

     

     

    I also have done a full system wipe and installed Yosemite 10.10.3 and these permission issues still return. I don't use an external display, but have done in the past with a Thunderbolt adapter.

     

     

    Did anyone managed a fix or the best thing to try? This couldn't be a thunderstrike issue could it?

     

     

    Many thanks to anyone who can help

     

     

    Group differs on “Library/Printers/InstalledPrinters.plist”; should be 80; group is 0.

     

    Permissions differ on “Library/Printers/InstalledPrinters.plist”; should be -rw-rw-rw- ; they are -rw-r--r-- .

     

    Repaired “Library/Printers/InstalledPrinters.plist”

     

    User differs on “private/var/db/displaypolicyd”; should be 0; user is 244.

     

    Group differs on “private/var/db/displaypolicyd”; should be 0; group is 244.

    Apple engineering has requested to launch the TimingSnoop.app and submit the output information in order to further investigate this issue.

    After this they sent me a new mail, "Engineering has determined that your bug report (20701735) is a duplicate of another issue (20800766) and will be closed". I suggest to submit to bug report your issues.

    I finally got it solved (my problem sudden computer shutdowns, and horizontal lines on screen, with computer something not accepting to restart... saw that displaypolicyd permissions was always faulty as I was trying to troubleshoot).

    It was actually a hardware problem: faulty video card covered by Apple recall: https://www.apple.com/sa/support/macbookpro-videoissues/

    My computer is a MacBook Pro 15" Early 2011.

    I got my computer to Apple's authorized distributor who replaced the motherboard for no charge (it took them 2 weeks ). I now it work fine.

    I hope this helps.

    I have the same issues - once I boot up, I can work normally.  After 1 restart however, I get this same permissions issue

    "User differs on private/var/db/displaypolicyd; should be 0; user is 244.

    Group differs on private/var/db/displaypolicyd; should be 0; user is 244.

    Repaired "private/var/db/displaypolicyd"


    When I shut down then restart the next day, the reboot stalls and I need to force shut down.  If I then start up in 'safe mode' I can run the permissions verification and repair, but then I only get to restart one time until a second restart stalls midway in the boot up and I must force shut down then restart in 'safe mode'.  Am I doomed to restarting in save mode everytime I  use this computer?  Its a Mac-Pro (Early 2008), 2 x 2.8 GHz Quad-Core Intel Xeon, 16GB Memory, Graphics card ATI Radeon HD 5770 1024 MB.  I am using Dual monitors.  This problem started on Aug. 12 after upgrading to Yosemite, have the latest 10.10.5 and have also erased the hard drive and did a clean install.  Still this happens everytime I start the computer.  Is there a permanent fix?

    I asked developers in bug report if the following displaypolicyd log is normal.

    u>52603393 ERROR: AGDC suppport not present in system

    u>52603463 ERROR: Policy engine instance init failed

    they said that "displaypolicyd log simply states system is not managed by AGDC and does not lead to any additional information about this panic report"
