Dear Stephen,
Sorry for the delay, I had other pressing work to do.
Thank you so much for looking at my patch!
What exactly was the problem on MacOSX? Where you getting compilation errors?
I just noticed the following line in src/AppleSpellChecker.cpp:
status == SPELL_CHECK_LEARNED ? LEARNED_WORD : WORD_OK ;
Which I should've changed to:
WORD_OK ;
If you can try and compile it and test it for me that would be great!
Although I'll try getting myself a Mac VM so I can do so myself.
The way the text is passed in chunks should hopefully not be a problem,
the main problem I see is what happens when you call this method
https://developer.apple.com/documentation/appkit/nsspellchecker/1525147-unlearnword
when you haven't previously called
https://developer.apple.com/documentation/appkit/nsspellchecker/1534837-learnword
The documentation dosen't explain sadly.
If my code doesn't work, I could always write a post-processing loop to check
for unlearned words, (which will be slower).
In fact that's pretty much what I made the Hunspell/Aspell backends do.
I should probably do some performance testing, but I've been using this patch
for a while now and haven't noticed any extra lag in spell checking.

Hi Isaac,
thank you for your work on LyX.
I’ve tried your patch and unfortunately it doesn’t work on Mac.
Despite the fact that it relies on the existence of the LEARNED_WORD in the
SpellChecker::Result enum there is IMO a problem with the general idea of the
solution with the Apple speller. Here the whole paragraph is passed as a big
chunk to the speller engine to get a reasonable performance.
Best regards,
Stephan
