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

sudo diskutil repairPermissions /

After repairing permissions problem reappears after a reboot.

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

Did it solve the issue?

On the macrumors thread someone reported the issue also happens at clean installs

This helped me - AirServer.app delete/quit

Oh man, I had AirServer installed as well. That might also have been my problem.

make sure you have the latest dropbox. they released it a few months after the yosemite release to deal with yosemite related issues. so far it has worked like a charm.

I updated Dropbox to 3.0.3 a few weeks ago. It seemed to help for a bit; but, it didn't last. I see 3.0.4 is out now, so I'll give that a try.

Dec 25, 2014 9:05 AM in response to SmithersJr

Nope, Dropbox 3.0.4 is doing the same thing. :-(

Goodbye, Dropbox. :-/

Dropbox installed. Repaired permissions. Running fine.

I haven't tried putting the MBP to sleep yet, though.

So has anyone actually managed to pinpoint the cause of this yet?

Dec 28, 2014 11:02 AM in response to James Random

Well, the last couple of times I removed Dropbox, my problem was resolved. But, with this latest time I removed it, the problem is still happening. :-/

Dec 28, 2014 1:01 PM in response to kraen

Run a check again, see if it has returned.

I don't have any problems with what I was having a problem with since I did the repair, but the errors still keep coming back.

This sounds reasonable. But why keeps Finder + Safari crashing again and again?

ANyone tried 10.10.2 clean install? Problem still there?

I also tried this solution. No issue on day 1. On day 2, same kernel panic...displaypolicyd.

You had this problem on the early 2015, 13" macbook pro?
