About developer

Atfer releasing macOS Catalina, I know that many people watching this and there are so many issues. But I am preparing Winter I-SURF at the University California of Irvine now... I am really newbie in English so I am studying English for interview.

I can't read all issues and reply them. Really sorry about this.
