Dock process taking up 100% CPU and event log error every second

[Warpyb1]

Having just recently purchased my new 2012 mbp13 I have noticed that process dock is taking up 100% CPU along with display device unknown in the event log. This is being logged every second - so much so that console stops reporting the events.

Anyone seen this ? A force restart of dock resolves the issue.

Delete these:

/Users/yourusername/Library/Preferences/com.apple.dock.plist
/Users/yourusername/Library/Preferences/com.apple.desktop.plist​

Then in Terminal, type the following, followed by pressing enter:

killall Dock​
