Out of date dictionary’s?

In my story I am using a combination of modern and antiquated words that do not appear in the dictionary pre-installed Apple OSX10.9. I am finding more and more that these words do exist in paper copies of dictionary’s meaning that I have to spent time away from reading and editing to go and check the existence of these words.

Come on Apple get your finger out and fix the PROPER BRITISH ENGLISH dictionary and not the out of date American crap that seams to be installed!
