Is there a bug/radical difference in how Mojave treats date settings in System Preferenceas from previous versions? All my 3d party apps on Mojave, except Launchbar, seem to be unable to interpret/render/paste date formats according to System preferences (Norwegian). I have next to no knowledge on this, but apart from Apple's own apps – wether built in or downloaded – they all render/interpret dates exclusively in British format dd/mm/yyyy, Monday, March, etc. System Preferences display correct settings/as expected for Norwegian (dd.mm.yyyy, mandag, mars, etc.), I also removed English as language pref entirely (I originally had it as my second option).
