Apple provides a spell checker architecture in Mac OS X. It would be nice if
Mozilla could use that spell check service.

What is the architecture under Mac OS X? Is it anything related to the OS Classic Word 
Services architecture I requested in bug 67208?

I don't think this is really a dupe of bug 58615.

Comment 5

Reopening as I suspect this is not exactly the same as bug 58615.

This bug probably depends on 58615. That bug appears to be about opening up the
spelling checking system to outside components, while this one is specifically
about hooking up to Mac OS X's built-in spelling checker Service; an alternative
to bundling yet another spelling checker with an application.

Reassigning to Kin per Beppe for re-evaluation. Kin, please see my Comment #5.

I've also added the URL for the relevant Apple developer documentation.

...and, since Fizzilla is still Carbon rather than Cocoa, see also

Making noise... 

Apple Spell is already there for the using, by default, on all OSX
installations. Mozilla should take advantage of this for the email client and
save itself from more memory bloat (at least comparitavely to other platforms)

In NSTextView there is a method, -

that should do what you need to do, or take a look at the documentation.  Good
Luck & keep up the good work.

I don't have any code to offer, but the lack of spellcheck is the _only_ reason
Safari is still in my dock!

This is absolutely NOT a duplicate of 58615.  That's "Need to investigate sharing the XP portion of the Netscape 6 spellchecker."  

If that was worked on it wouldn't even touch this one.  Super! It works on XP.  Not on the Mac.  

The Macintosh Operating System has a spell checker built-into it, available to every Carbon application.

Still using Safari just because of this real deal-breaker.

Process question... How can an issue entered in 2001 still be in the status "New"?

If this isn't going to be addressed, let's mark it WONTFIX.

This was already fixed by bug 151040 (for all apps, not just Camino).

But the osxspell code doesn't allow to switch the dictionary language, and OS X only ships 14 dictionaries or so, but we need a lot more.
So bug 422760 reverted that and made us use hunspell on all platforms and apps except Camino, which still uses osxspell.

Reenabling osxspell requires fixing bug 419959 (allow to switch the dictionaries) and a solution for the missing locales, like third-party OS-level dictionaries, or converting the hunspell dictionaries to OS X dictionaries.

However, the spellcheck code first needs an active, dedicated developer (owner).
Depends on: 151040, 419959

Found this bug and I also think this would be a good improvement. Because the mozilla spell checker in Thunderbird doesn't work very well for me at the moment. I hope there is a solution for the problems mentioned in #22. 
But the url at the top is a way old, I think. Don't know what the original page was, but this seems newer:

A big plus of the OS X spell checker is that it can guess the used language.  It actually even handles multiple languages in the same text component quite fine.

For reference, old (Camino-specific?) code to this effect was removed in
What languages does the macOS system spell checker support that Hunspell doesn't, except Finnish? (At least as of El Capitan, the macOS system spell checker support for Finnish is inferior to Voikko [Ubuntu/Debian system spell checker for Finnish] and the Windows 10 system spell checker for Finnish.)

What languages does the macOS system spell checker support better than Hunspell does?

It's not about better support or more languages, it's about the lack integration with the OS which makes the product unattractive.

Users get used to a spell checker and want to use the same everywhere. They don't want to re-learn a new interface just for your product.

Users also train and add words to the native spell checker. Absolutely no one wants to start that work again with each new program that decides to bundle its own service that the OS already provides.

If you don't take OS specific integration seriously, your users will not take your product seriously.
