On my iOS7 devices (iPhone 5, iPad Air), I added a Korean keyboard and I can operate it effectively.
On the Macbook Air, I added the "3-Set Korean" input source and I cannot operate it effectively. (Some characters are not available, and those that are do not stack correctly. I am a beginning Korean writer.)
How can I get the iOS7 version of the Korean keyboard, or something very like it, to work on OSX Mavericks?
