Just trying to help.

Try going to:

Apple menu > System Preferences

then on the top line

> Language and Text

Try changing the settings via the tabs at the top as follows:

Language: Everything says English and English is the top of the list.

Text > Spelling (drop down menu on the right hand side): set to British English

Formats > Region > United Kingdom

Input Sources: Make sure British is the only checkbox selected.


Give that a go, and don't forget to change your application preferences too.
