Mavericks brings yet another version of Apple’s OS X and the continued existence of Dashboard confuses everyone. Here’s how to completely turn it off:
$ defaults write com.apple.dashboard mcx-disabled -boolean YES
Also for the hardcore — Completely turn off Desktop:
$ defaults write com.apple.desktopservices DSDontWriteNetworkStores -bool true
The folder will still exist it just wont be your desktop. You might have to re-log in for it to take effect. With these two power-settings you’re ready to concentrate and do your best procrastination on something better than files or widgets – fx Twitter.
