To run the latest version of Xcode, make sure you are launching Xcode.app from the Applications folder. Xcode 4.3 and later is packaged on the Mac App Store as a single application and installs in your Applications folder as Xcode.app. Previous versions of Xcode placed the tools and frameworks in the Developer folder. Ever since Lion (OS X 10.7), Apple has hidden your personal Library folder (/Library) by default. In Lion and Mountain Lion (OS X 10.8), you could make the folder visible, but it required some work.

The OS X operating system combines a stable core with advanced technologies to help you deliver world-class products on the Mac platform. Knowing what these technologies are, and how to use them, can help streamline your development process, while giving you access to key OS X features.
At a Glance
This guide introduces you to the range of possibilities for developing Mac software, describes the many technologies you can use for software development, and points you to sources of information about those technologies. It does not describe user-level system features or features that have no impact on software development.
When we took the screenshot, the program automatically created a folder on our desktop and stored it there.You can't add any other information, such as ISBN or publisher, or insert any notes, so serious hobbyists or collectors will probably want more; but those looking for ease might like the streamlined approach of My Library for Mac. Additionally, the user is able to perform a quick search within the app based on a search string, sort titles and authors, and take a screenshot of their library.

My Library for Mac takes the less-is-more approach, enabling the easy creation of a very basic catalog of the books you own.The app greeted us with a very clean and intuitive interface.
OS X Has a Layered Architecture with Key Technologies in Each Layer
It’s helpful to view the implementation of OS X as a set of layers. The lower layers of the system provide the fundamental services on which all software relies. Subsequent layers contain more sophisticated services and technologies that build on (or complement) the layers below.
Mac Os X Versions
The lower the layer a technology is in, the more specialized are the services it provides. Generally, technologies in higher layers incorporate lower-level technologies to provide common app behaviors. A good rule of thumb is to use the highest-level programming interface that meets the goals of your app. Here is a brief summary of the layers of OS X.
The Cocoa (Application) layer includes technologies for building an app’s user interface, for responding to user events, and for managing app behavior.
The Media layer encompasses specialized technologies for playing, recording, and editing audiovisual media and for rendering and animating 2D and 3D graphics.
The Core Services layer contains many fundamental services and technologies that range from Automatic Reference Counting and low-level network communication to string manipulation and data formatting.
The Core OS layer defines programming interfaces that are related to hardware and networking, including interfaces for running high-performance computation tasks on a computer’s CPU and GPU.
The Kernel and Device Drivers layer consists of the Mach kernel environment, device drivers, BSD library functions (
libSystem), and other low-level components. The layer includes support for file systems, networking, security, interprocess communication, programming languages, device drivers, and extensions to the kernel.

You Can Create Many Different Kinds of Software for Mac
Using the developer tools and system frameworks, you can develop a wide variety of software for Mac, including the following:
Apps. Apps help users accomplish tasks that range from creating content and managing data to connecting with others and having fun. OS X provides a wealth of system technologies such as app extensions and handoff, that you use to extend the capabilities of your apps and enhance the experience of your users.
Frameworks and libraries. Frameworks and libraries enable code sharing among apps.
Command-line tools and daemons. Command-line tools allow sophisticated users to manipulate data in the command-line environment of the Terminal app. Daemons typically run continuously and act as servers for processing client requests.
App plug-ins and loadable bundles. Plug-ins extend the capabilities of other apps; bundles contain code and resources that apps can dynamically load at runtime.
If your library is badly damaged and the preview is missing a lot of content from the original library, this can save you from going through with a rebuild that won’t end up being of much help.Once you've had a chance to examine the preview, if you want to go forward and create the rebuilt library, click the 'Rebuild' button in the upper right. IPhoto Library Manager will create a new library and start importing the contents of the original library into the new one.Scavenging photosIn some cases, either the iPhoto library database is too damaged for iPhoto Library Manager to be able to salvage any information from it, or the library data is incomplete and there are photos that still exist inside the library package, but iPhoto has lost track of them.
In these cases, you may want to check the 'Scavenge orphaned photos' checkbox when choosing a location for the rebuilt library. Once you've made your choices, iPLM will examine the library and rebuild the library structure and photos as best it can, then display you a of what it was able to find.System plug-ins. System plug-ins, such as audio units, kernel extensions, I/O Kit device drivers, preference panes, Spotlight importers, and screen savers, extend the capabilities of the system.

When Porting a Cocoa Touch App, Be Aware of API Similarities and Differences
The technology stacks on which Cocoa and Cocoa Touch apps are based have many similarities. Some system frameworks are identical (or nearly identical) in each platform, including Foundation, Core Data, and AV Foundation. This commonality of API makes some migration tasks—for example, porting the data model of your Cocoa Touch app—easy.
Other migration tasks are more challenging because they depend on frameworks that reflect the differences between the platforms. For example, porting controller objects and revising the user interface are more demanding tasks because they depend on AppKit and UIKit, which are the primary app frameworks in the Cocoa and CocoaTouch layers, respectively.

The OS X Developer Library contains the documentation, sample code, tutorials, and other information you need to write OS X apps. You can access the OS X Developer Library from the Apple Developer website or from Xcode. In Xcode, choose Help > Documentation and API Reference to view documents and other resources in the Organizer window.
In addition to the OS X Developer Library, there are other sources of information on developing different types of software for Mac:

Apple Open Source. Apple makes major components of OS X—including the UNIX core—available to the developer community. To learn about Apple’s commitment to Open Source development, visit Open Source Development Resources. To learn more about some specific Open Source projects, such as Bonjour and WebKit, visit Mac OS Forge.
BSD. Berkeley Software Distribution (BSD) is an essential UNIX-based part of the OS X kernel environment. Several excellent books on BSD and UNIX are available in bookstores. But you can also find additional information on any of the websites that cover BSD variants—for example, The FreeBSD Project.
Third-party books. Several excellent books on Mac app development can be found online and in the technical sections of bookstores.
