By default Dashboard appears as the first Spaces in mission control. If you are not a Dashboard user, you can hide Dashboard from appearing as Spaces with the following command:
defaults write com.apple.dock dashboard-in-overlay -bool true
To make the command take effect, you need to restart the Dock
killall Dock
You can activate Dashboard with the F12 or F3 key.
Revert to the default setting:
defaults write com.apple.dock dashboard-in-overlay -bool false
How do I stop dashboard from zooming in/out when it is activated/inactivated? It gives me nausea if I forget to shut my eyes.
