Getting Started with Mac OS X

By Tim Holmes

The first and more important thing you should know about Mac OS X is that it is coming soon! A public beta of Mac OS X was released in September and Apple will deliver the first commercial release of Mac OS X in early 2001. For overall information about Mac OS X and developers, please visit:

http://developer.apple.com/macosx/

This article presents you with many options for Mac OS X development. Ultimately, however, you will need to make your own choices, factoring in current code base, time to market concerns, and platforms to be supported.

The Apple Developer Connection

is pleased to present a new series of articles specifically designed to help facilitate your Mac OS X development. In the upcoming months, Apple's Technology Managers will present articles covering topics such as

the Cocoa and Carbon APIs, Apple's new development tools, I/O Kit, Quartz, Aqua, and more.

These articles will present an overview of key Mac OS X technologies with pointers to online resources from Apple that provide more in-depth information. Accompanying the feature articles will be sidebars and helper articles to help you more effectively navigate Apple's technical documentation and to teach you shortcuts and tips that will improve your code and accelerate your development.

Whether you've already investigated moving your products to Mac OS X or not, these articles should help you get started and resolve open issues.

Forks in the Road

Before you begin, you will need to know the answers to the following:

  • What platforms will you support -
    Mac OS 9, Mac OS X, Unix, Windows?
  • Are you writing an application, a driver, creating a system extension, etc?
  • Do you have a preexisting code-base? How large is it? Is it in need of an overhaul?

Your answers to these questions will help you choose the most effective development path, and ultimately deliver a better Mac OS X product.

Let's begin with the most common scenario; you're a Mac OS application developer who already has code based on Mac OS 9 or earlier. There are two most likely paths for you. You may use Carbon, the modern set of APIs founded on the traditional Mac OS APIs, or you may use Cocoa, the newer Mac OS X-only object-oriented APIs.

Carbon

The best route for your product depends primarily on your time to market and platform needs. While Cocoa allows you to build your application more efficiently and quickly, you may not have the time to rewrite your application in a new framework. If this is the case, Carbon may be your best route. You can find out how to get started carbonizing your application at:

http://developer.apple.com/techpubs/macosx/Carbon/carbon.html

Cocoa

If you have the time to redesign your application to take advantage of a modern object-oriented framework and would like to produce a Mac OS X-only application, the rapid development tools and robust Cocoa framework will let you create a superior Mac OS X product.

If you currently have very little code written or none at all, and you are interested in creating a Mac OS X-only solution, then you should investigate Cocoa. It's definitely worth investing the short amount of time it takes to come up to speed. For information on Cocoa development, visit:

http://developer.apple.com/techpubs/macosx/Cocoa/CocoaTopics.html

Driver Development

On the hardware side, the I/O Kit for Mac OS X provides Mac developers with a new, much easier way to create drivers. Remember, however,

that what you may have once thought of as a driver under Mac OS 9 may not be considered a driver under Mac OS X. You can find out all you need to know on this topic under the Kernel heading at:

http://developer.apple.com/techpubs/macosx/macosx.html

System Extensions

Finally, if you are considering extending or customizing the operating system, there are numerous ways to do so. In order to create a more stable platform, some changes were made to Mac OS X that make the methods you may have used for Mac OS 9 no longer applicable. For more information about this topic, please see:

http://developer.apple.com/technotes/tn/tn2003.html

New to the Mac?

Because Mac OS X combines support for a variety of technologies beyond those typically associated with the Mac, it presents non-Mac developers with some interesting new opportunities as well.

Java Developers

Mac OS X has an incredible implementation of Java 2, providing you with a consumer desktop platform for your Java applications and applets. If you wish to create a Windows/Mac OS compatible solution, Java very well may be your best route. What's more, via JFC/Swing, you can get Mac OS X's Aqua interface for free. You'll find information and documentation on Java development on Mac OS X at:

http://developer.apple.com/techpubs/java/java.html

UNIX Developers

If you already have a UNIX code base, Mac OS X presents a great opportunity for you. You can quite easily move your application to Mac OS X by taking advantage of the FreeBSD 4.4 APIs that Mac OS X is based upon. If you wish to quickly get your product up and running on Mac OS, simply port your application to these APIs. However, if you are interested in attracting current Macintosh users, you should move the engine of your product over to Mac OS X, and write a Cocoa GUI that will take advantage of Mac OS X's features. To accomplish this, see the Cocoa documentation mentioned above and the BSD documentation below:

http://www.unix-systems.org/online.html
http://www.netbsd.org
http://www.freebsd.org

XWindows Developers

If you have an XWindows product, then you're in luck as Tenon's XTools allows an XWindows solution to run unmodified, while still taking advantage of some of the native Aqua features of Mac OS X. For information on Tenon's product, visit:

http://www.tenon.com/products/xtools/pre-release_beta/

Discounts on Mac OS X Migration

Bring Your Apps to Mac OS X

With Mac OS X Public Beta here, and the commercial release just over the horizon, Mac developers everywhere have a huge need for Carbon and Cocoa application porting, Aqua user interface implementation, and driver development services. Several high-quality software engineering firms, in association with the Apple Developer Connection, are offering these services at very attractive discounts to all ADC Select and Premier members.

http://developer.apple.com/mkt/macosxmigration.html

End-User Tech Support

We all know how expensive and time consuming it is to set up and maintain a comprehensive customer tech support department. To support developers in their migration to Mac OS X, 877MacTank has designed an exclusive and affordable tech support staffing program for ADC Premier and Select members.

http://developer.apple.com/mkt/mactank.html

Until Next Time

Each of these paths to Mac OS X has alternatives, pros and cons, and each may fit one developer's needs better than another's. Once you have fully investigated your options and decided which path is right for you, it's time to get to work. And yes, there is work to be done, but that is where we can help you succeed.

We'll be covering more specific technologies in the upcoming articles. In the meantime, we welcome your suggestions on how to make how to make these articles more useful for you. Feel free to send email to me, Tim Holmes, at <shortstop@apple.com> with your comments.

See You Next Month.

Did You Know?

Developer Help Center

When it comes to programming for Mac OS X, do you feel like an explorer on the shore of a vast new continent? Don't worry, there are "charts" to guide you-the developer documentation you get when you install the Developer package.

You can access this information through the Developer Help Center, a section of the Help Viewer application. To get to it, first open the (user) Help Center by choosing Mac Help from the Finder menu. Then click the "Developer Help Center" link at the bottom of the page.

The Developer Help Center works just like a Web browser. You can either navigate through the sets of documentation by clicking links or you can search for specific information. Searching is as simple as typing text (phrases, words, or API symbols) in the field at the top of the application and clicking the Ask button. The search engine returns a weighted list of "hits" (links) you can browse through. The Developer Help Center also lets you focus your searches on the set of documentation you are interested in. Thus a search when you are perusing Carbon documentation confines the results to Carbon. If the results yield nothing of interest, you can easily expand the search to the complete set of documentation.

There are some known bugs in the Public Beta version of Help Viewer; see the release notes for details.
