Ever called up a HelpViewer window in an app only to find that you have to close the window in order to get back to the app and start following the instructions? That can be highly annoying if the instructions aren’t easy to remember.
That’s because the HelpViewer.app is by default set to always be on top. If you want to change that, here’s a nice little Terminal trick that will let you manage HelpViewer windows just like a normal window, courtesy of new tipster site defaults-write.com. Here’s what you do:
1. If you have any HelpViewer windows open, close them first.
2. Open Terminal.app (/Applications/Utilities/Terminal.app) and paste this command into the window:
defaults write com.apple.helpviewer DevMode -bool true
and press ‘return’ on your keyboard.
That’s it! From now on, you’ll be able to switch focus between the app and the HelpViewer window so that you can work with whichever one you need on top.
Tip: If you want to reverse the behaviour, use the same command as above but replace ‘true’ at the end with ‘false’.
