I see many threads on how to change the language setting on this forum. But, I would like to ask this simple question as those threads did not touch this particular question specifically. Is OS X basically same in any country Apple is selling through its established sales channel, except for the default language setting? Is there any difference in the OS X's coding based on the country Apple is selling Macs? If OS X is same globally and if you keep all the languages preloaded in OS X, you can install any Mac apps (by Apple and other software vendors) even if the software's menu and interface is written in the language of that particular country. Or, am I wrong on this?
