NGUI version :3.11.1
Unity version :5.5.0f3
FreeType version:2.7.1/2.6.5

I install freetype with brew in OSX, changing the filename to "FreeType.dylib" from "libfreetype.6.dylib"
and i still crash in line  showed above.

how can I do with this issue?

I'm pretty sure you need a specific version of FreeType. I don't know what version comes with the OSX. Try getting the FreeType from https://www.freetype.org/ and compiling it yourself.

I download the newest freetype and compile it, and still crash when I use the FontMaker.
My FreeType version is 2.7.1.
I want to know which version  work well with the NGUI on OSX?

I believe it was FreeType 2.5, but it's been so long that I'm not sure...
