What is the Mac Dev Center?
The Mac Dev Center provides a complete set of resources for developing and distributing Mac apps, including software downloads, the Developer Certificates Utility, getting started videos, sample code, and access to a wealth of technical documentation in the Mac OS X Reference Library.
Can I obtain code-level technical support for development with pre-release software?
While code-level technical support for pre-release software is not available from Apple, members of the Mac Developer Program can post their questions to the Apple Developer Forums. Additionally, the Mac Dev Center provides links to technical resources that can assist you with your development. You may also file a bug report if you feel that you've identified a bug or would like to file an enhancement request.
I'm not a Mac Developer Program member, but I am registered as an Apple Developer. What do I have access to?
As a Registered Apple Developer, you have access to Xcode Tools, as well as select resources and information on the Mac Dev Center.
For access to benefits like pre-release software, access to Developer Forums, and Developer Technical Support, you will need to join the Mac Developer Program.
