British Dictionary
I finally looked up how to stop it (without right-clicking on each word and having the Mac learn it).
If you’re British too and want to banish those red underlines. Here’s what to do:
Open System Preferences and select International.
Click on Edit List...
From the drop down window tick British English and
press OK. Make sure: Order for Sorted Lists, is set
to English.
Log out or restart and you’re done.
Update: A much quicker way comes from Christopher
Phin of MacFormat:
“...an easier way to
switch to British English is
to right-click on any word, choose Spelling and
Grammar > Show Spelling and Grammar and then
switch from 'English' to 'British English'. Hardly
obvious, but an essential tweak for a new Mac!”
I don’t think
I’d’ve ever found that one. Thanks to
him.
