Here are a few interesting
defaults write commands that I have applied to my Apple Macintosh
$ defaults write com.apple.finder AppleShowAllFiles TRUE - show hidden files
This command turns on the display of hidden files in the Finder. This is particularly useful when dealing with so called “dotfiles” or configuration files that are normally hidden.
$ defaults write com.apple.finder _FXShowPosixPathInTitle -bool YES
This setting causes the full path of the currently displayed directory to be shown in the title bar of the Finder window.
$ defaults write com.apple.iTunes allow-half-stars -bool TRUE
With this setting enabled you can click on the rating for a track in iTunes and slide until you have
$ defaults write com.apple.Safari IncludeDebugMenu 1
Debug menu on.
$ defaults write com.apple.Safari TargetedClicksCreateTabs -bool TRUE
Enabling this option forces all links that have a target to open in a new tab rather than in a new window.
