Here is how to move your Dashboard Stickies widget information to a new user or a new Mac OS X system. All the text you wrote on the Stickies is contained in the /Users/[your_username]/Library/Preferences/widget-com.apple.widget.stickies.plist file.
First, you’ll need to copy that file someplace visible so you can transfer it to the other location.
You can to this using Finder, or by opening a Terminal window and typing this:
cp ~/Library/Preferences/widget-com.apple.widget.stickies.plist ~/Desktop
The ~ character is the UNIX shortcut to the current user’s home folder, that is /Users/[yourusername], and this command will copy the Stickies data file to your Desktop.
Note: Before you move the file to the new user / system, make sure you have at least one Sticky note active on your destination dashboard, as the file you are going to copy will get overwritten the moment you add the first note to the dashboard.
The next file you need to copy is the com.apple.dashboard.plist, the Dashboard’s global config file. Copy the plist to your Desktop as well:
cp ~/Library/Preferences/com.apple.dashboard.plist ~/Desktop
Now move the files to the other computer, and put them back into the ~/Library/Preferences/ folder. Don’t rush to your Dashboard yet though, as the changes are not immediate and you need to reload the Dashboard, and the easiest way to do that is to restart the Dock.
Type the following in your Terminal window:
Now your Dashboard should load and show your old Stickies with your texts.
