This is the method I used: Disable Dashboard

Controlling the dashboard. Sometimes you just don’t want it around.

Note: This is a per user setting. I do not know how to disable it by default for every user. Possibly if you make this change to /Library/Preferences/com.apple.dashboard –

Make Dashboard go away

defaults write com.apple.dashboard mcx-disabled -boolean YES

Make Dashboard come back

defaults write com.apple.dashboard mcx-disabled -boolean NO

You have to restart the Dock to have this take effect

killall Dock

The terminal is your friend.

– Dashboard has been burning CPU and eating memory, and it’s impacting my uptime. I have to wonder what’s up?
