Lost Dock using Terminal

[Joleen28]

I subscribe to Mac Life and in the newest issue there is an article called 25 Top OS X Terminal Tips:

I attempted to do #14 Recently Used. I typed the command:

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'; killall Dock

After I executed the command my Dock disappeared and my computer locked up. I turned my computer off and back on but my Dock is still gone and after about 2 mins my computer locks up again. Can someone please tell me how I can fix this?

Reinstall OS X or restore your machine from a backup.

you could try moving ~/Library/Preferences/com.apple.dock.plist to the desktop and rebooting, while I don't know for sure about his file, macos tends to replace missing plist files

That seems a bit... drastic....

Remove the dock plist as recommended above, or type this in terminal:

defaults delete com.apple.dock persistent-others

That blows out the left side of your dock which is where the recents stacks live.
