Apple Seeds Mac OS X Leopard (9A581) to Developers

With the launch of Mac OS X 10.5 Leopard to customers, Apple has finally seeded the Gold Master version of Mac OS X Leopard (Client and Server) to developers. It represents the same version of Leopard that is shipping to customers.

Mac OS X 10.5 Leopard (9A581) is now available to Select and Premier developers. Apple had last seeded build 9A559 to developers on September 21st, 2007.

Some developers had been critical of Apple withholding the final version of Leopard from developers. Keeping the final build of Leopard internal, however, did not prevent its leak in the days leading to its release.

Apple Leopard launch events are still taking place across the U.S.

Its odd that it didn't come earlier, especially considering that the build was pirated days ago...its a pity that so many apps don't work...

First time I've ever heard of any OS getting released to consumers before businesses/developers. A bit odd business model if you ask me, though I doubt it makes much difference in the long run.

Grrrrr. I asked Apple about this and they basically told me they weren't telling when Leopard was going to be released. Being the early adopter that I am, I bought my version today. At least I got a t-shirt. :D On the flip side, I do have 4 computers to install on, so the Family pack was the more ethical choice.

I Certainly hope Apple is understanding the concept of Developers needing the most up-to-date code to make apps better.

It likely is not that different at all from the previously release beta build anyway.
You cant blame Apple for holding back on the final for a few days to developers, in order to reduce piracy.
Tiger was freely and easily available all over the net for well over a week (maybe 2) before it was released for sale. That must have had some impact on sales for sure. Which has been largely confirmed by early sales figures of Leopard compared to Tiger.

It's nice that it's still not available to student developers...at least Apple could have given us an answer as to when it would be made available.

I was *so* hoping it would be, too.. :(

wishful thinking, I know.
