Hangeul(Korean script) input system doesn't work properly in Mac OS X El Capitan. The letters don't input by syllables but particularly.
For example: "가, 고, 거" shows to "ㄱㅏ, ㄱㅗ, ㄱㅓ"

Having played official 1.9 and tested Hangeul input in Internet Café, I opened the game in Mac OS X El Capitan
What I expected to happen was the letters were shown properly as same as in Windows

But What actually happened was the letters were typed particularly and not gathered in syllable form.

So this is how did it happened.
1. Opened the chat box
2. Typed any Hangeul letters
3. Letters won't gathered properly
