Snow Leopard’s shrinking mail.app: Mystery solved
Wednesday, June 25th, 2008
Someone, who seems to have some personal knowledge of Snow Leopard, claims to have solved the mystery of Snow Leopard’s shrinking mail.app.
In a post that details the various myths
doing the rounds on the shrinking apps—no PPC code (false!), smaller binaries (false!), missing language files (false!)—the writer spills the beans:
When you look in Mail.app you see that language files use up most of the disc space. Inside the language folder (e.g. “German.lproj”) are a lot of .nib files (the extension of Interface Builder). Inside normally are two files. One is a very small “keyedobjects.nib” and the other is very big “designable.nib” file… Now the “designable.nib” is gone. It seems like it had no reason other than to give hackers a chance to mess with the application’s UI design.
I guess he is referring to these two files which are inside each (c. 84) folder within every (18) lproj localisation folder, as in this example from the English.lproj GeneralPreferences.nib folder:

Perhaps this is as false an explanation as all the others.
Still, it has enough specifics, specifics that only someone with access to a build of Snow Leopard could know, to lend the story credence.
