As mentioned, "Monolingual" but read the FAQ at the site, especially if you have the latest Adobe and MS Office 08 installed. They won't update properly if the languages are missing.Hey Folks.
How can i remove all the language that I know i will never need...? The reason I'd like to remove it is to free up space, if that's even possible?
And the key name for the language folders ends with ".lproj" which you can search for using "EasyFind". Just DO NOT remove any 'english.lproj' or 'en.lprog' folders. Your Mac won't run if you do. So - if in doubt - don't delete.
Before running Monolingual, use your International pref pane and use the Edit button and un-check all but the various english languages and Monolingual will automatically have all but those selected in the languages tab. But DO check the Monolingual language list for other 'english' variations you might have.
PS: Your attached pict shows the 'imput' tab selection. Those are keyboard mapping layouts and not "languages".
With all the other stuff that Monolingual can remove, one can usually save 2-3 GB of HD space!! ;-)
