Included in the new and improved Mac Developer Program is access to prerelease builds of Mac OS X, member-only developer forums, a series of instructional videos from Apple engineers, and two direct technical support incidents per year. The TSIs give developers direct access to an Apple engineer for assistance with code problems or other troubleshooting, and developers have the option of buying additional TSIs as needed.
The new program replaces the previous ADC Premier, Select, and Student developer programs. The biggest difference between the new and old programs, aside from the much lower price, is the loss of the ADC Hardware Purchase Program benefit that offered steep discounts on Macs for the Select and Premier account holders. Some developers have already said that they'll happily take the lower cost of entry over the hardware discount.
Premier accounts, which cost over $3,000, also used to include one free ticket to Apple's Worldwide Developers Conference, which normally cost $1,200. Ostensibly, any Mac Developer Program member will have a chance to buy a ticket next year (at least until it sells out, like it has the past two years).
The lower barrier to entry is expected to spur an influx of Mac developers, much as the iPhone Developer Program did. Developers familiar with developing for the iPhone should have a relatively easy time of transitioning to developing for the Mac, since both use the same Xcode IDE, Objective-C language, and many similar APIs (though obviously UI considerations are quite different).
Current ADC memberships remain in effect until they expire. Developers that bought an ADC membership after Feburary 1 can contact Apple to get a refund if they wish to join the Mac Developer Program instead. The Mac Developer Program will be the only program Apple offers going forward. Basic access to Xcode developer tools and released versions of Mac OS X SDKs remains free.
