For instance, I want to copy my Expose settings to another mac, as well as power management, appearance, and a couple of other things. Is this possible? If so how do I do it?
You'll find most system preferences in
/Library/Preferences/SystemConfiguration, and user
~/Library/Preferences/. For OS X most settings files will start with
com.apple. To view the contents of such
.plist files, you need Property List Editor (included in the Apple Developer Tools), or use
plutil to convert it.
The Energy Saver settings are in
com.apple.PowerManagement.plist. I guess Exposé might be included in the Dock preferences,
com.apple.dock.plist. Its key bindings are in
I'm not sure if copying the whole files is a good idea; surely you first need to peek into them to see what else is configured.
com.apple.systempreferences.plist mainly holds the preferences of the System Preferences itself.)
