Como comienzo a desarrollar en Mac?

Muchos desarrolladores que conozco están migrando al mundo
Mac y frecuentemente nos preguntan a las personas que llevamos tiempo
programando en esta plataforma como comenzar.

Hoy Daniel Jalknut publicó en su blog un artículo con las siguientes
recomendaciones:

When newcomers to programming on the Mac ask me for advice about getting started with Cocoa, I usually boil it down to three steps, depending on the amount of time and money they are prepared to put into the task:

1. If you’re the slightest bit curious, buy Mark Dalrymple and Scott Knaster’s affordable book, Learn Objective-C on the Macintosh. It’s great that this book not only starts from the very beginning, but is available as an easy electronic download, for instant gratification.
2. If you’re convinced you’re in for the long haul, but prefer to learn at your own pace and in your spare time, pick up Aaron Hillegass’s Cocoa Programming for Mac OS X.
3. If it’s time to put the pedal to the metal, and you want to minimize the chances of failing as you learn the basics of this art, drop everything and enroll in the Objective-C and Cocoa Bootcamp class at Big Nerd Ranch.

Personalmente yo agregaría dos libros más:

1. Become an Xcoder
2. Cocoa Programing

Ambos son libros electrónicos que también ayudaran a ampliar sus habilidades como Cocoa Developers.
