This book is a large step forward in facilitating that combined knowledge. While introducing UNIX developers to the tools available under Mac OS X at a favorite price point (., free), it also shows Macintosh developers how to adapt to this new environment and make the most of the new tools now available to them. While the transition from UNIX to Mac OS X may seem daunting, this book is a gentle guide, highlighting the development issues found along the way and smoothing the sometimes serpentine path of coding we all travel.
