About the Author

John Ray is a life-long fan of Apple products; he has been an avid Mac user since its inception in 1984. He relies on OS X both at work and at home because it is a robust, flexible platform for programming, networking, and design. Over the past 15 years, John has written books on OS X, iOS development, Linux, web development, networking, and computer security. He currently serves as the Director of the Office of Research Information Systems at The Ohio State University. When he isn’t writing, he is either re-creating a marine disaster in his living room, or planning a highly elaborate electronics project that will quadruple his carbon footprint.
