Wrapping word configuration in mac

Solution 1:

From the Apple menu choose "System Preferences…", click on "Language & Text", and then click on the tab labeled "Text". From the pop-up menu "Word Break" choose "English (United States, Computer)" and relaunch the applications you want to test this in. This should work at least in all Cocoa-Applications, and I tested it in Smultron (sourceforge variant) too.
