Prevent OS X help windows from hogging your screen

prevent os x helpviewer from taking up your whole screenOver the years of delivering Mac Training for Apple through Amsys, I often get asked how to disable something or change how a default feature works, more than how to configure something!
Have you ever selected the ‘Help’ menu in the Finder or in an Application on your Mac and noticed that the Help Viewer window will open and always stays in front of all your other open windows?
I find this rather annoying, but luckily there’s a simple command to force the Help Viewer windows to start acting like every other window!
So, all you have to do is open the Terminal Application from /Applications/Utilities and enter the following command:

defaults write com.apple.helpviewer DevMode -bool true

Now, isn’t that better? Now you can have the Help Viewer open but not have it stay in front of all your other windows!
If you do want to revert back to the default setting, just enter the following command:

defaults write com.apple.helpviewer DevMode -bool false
