Top 15 Terminal Commands for Hidden Mac OS X Settings

Today i found this secret hidden tip from someone blog (later i will give credit to him ..heeheeh)



1. defaults write com.apple.Dock showhidden -bool YES

Makes hidden applications' dock icons translucent. NO to reverse.



2. defaults write com.apple.iTunes invertStoreLinks -bool YES

Normally the arrows next to artists and albums in your iTunes library search the iTunes store when you click them. This command changes them so that clicking will search your iTunes library instead. Put NO at the end to reverse.



3. defaults write com.apple.dashboard devmode YES

This allows you to drag widgets out of Dashboard onto the desktop. Requires the dock to be relaunched to take effect, so type "killall Dock" and press enter. Now, if you click and hold onto a widget in the dashboard and press F12 to return to the desktop, the widget won't disappear with the rest. Put NO at the end to reverse.



4. defaults write com.apple.mail PreferPlainText -bool TRUE

Forces all mail to be displayed as plain text. Replace TRUE with FALSE to reverse.



5. defaults write -g NSNavPanelExpandedStateForSaveMode -bool TRUE

Sets expanded save dialogs as default (showing column/list view of folders rather than a drop down menu). Replace TRUE with FALSE to reverse.



6. /System/Library/Frameworks/ScreenSaver.framework/Resources/ ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background

Displays the currently chosen screen saver to be shown as the desktop background. Press Control-C or Command-. to stop. More details here.



7. defaults write /Library/Preferences/com.apple.loginwindow AdminHostInfo SystemVersion

HostName



8. sudo defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add shortname1 shortname2 shortname3

To remove accounts from the login window type this command with the short name of each account you wish to remove. More details here.



9. com.apple.frameworks.diskimages skip-verify TRUE

Skip disk image verification. Potentially risky, use with disk images from trusted sources. Replace TRUE with FALSE to reverse.



10. defaults write "Apple Global Domain" AppleScrollBarVariant DoubleBothPuts
double scroll arrows at both ends of scroll bar. Use Appearance pane in system preferences to reset.



11. defaults write com.apple.CrashReporter DialogType none
