Author of numerous little Mac apps (and a blog).
Since April 21, 2014, I work for Apple, as a QA Engineer on the Foundation framework team. Answers and edits before that date were written before I knew anything internal. After that date, I'll be posting VERY sparingly (if at all), and only about APIs and behaviors that are public—i.e., verifiable in released software or promised by documentation.
Above all, nothing I write here, or anywhere else public, should be construed as an opinion or statement from Apple, nor a promise of future behavior or features. Opinions, when I give them, are my own.
