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.
