For those of us that have upgraded to 10.8 Mountain Lion and use Apple apps like Pages and Keynote you may have noticed that the default save location is always iCloud.
I tend to want to save to my local disk rather than iCloud so it would be nice to have these apps default to the local drive, you can change this with the following defaults command.
defaults write NSGlobalDomain NSDocumentSaveNewDocumentsToCloud -bool false
If you need to revert the setting the simply change the -bool option from false to true.
