I used to love using Dashboard in OS X. I occasionally use it on my work system but on my home iMac the Dashboard is just sitting idol wasting CPUs. It never bothered me until I installed Mountain Lion. I occasionally use the side-swipe on my mouse and hated ending up at the Dashboard. No longer an issue since I killed the Dashboard! Yep- It’s D E A D.
Disable Dashboard
- Open Terminal.app (Applications/Utilities/Terminal.app)
- Type (or copy and paste) defaults write com.apple.dashboard mcx-disabled -boolean YES;killall Dock
- Hit the Return key.
Enable Dashboard
If you decide you want the super useful Dashboard back in the future just change the boolean to NO.
- Open Terminal.app (Applications/Utilities/Terminal.app)
- Type (or copy and paste) defaults write com.apple.dashboard mcx-disabled -boolean NO;killall Dock
- Hit the Return key.
Simple!
