According to our earlier report, Apple recently seeded the OS X Mavericks Build 13A598 to members of the AppleSeed testing program. While Apple has been diligently releasing beta builds of OS X Mavericks, this was particularly interesting as it had dropped the “Developer Preview” tag from the name, suggesting that the software could soon be out of beta and a Golden Master build would be released soon. What we did not expect was that by soon, it meant only a few hours later. Yup, it looks like Apple has since posted the 13A598 build to registered Mac developers and are referring to that build as the GM build, which essentially would be the same version the end user can expect once it is released to the public.
As noted from our report earlier, this particular build did not contain major changes, but rather some minor tweaks and bug fixes, suggesting that the build was close to being out of beta. Apple had originally targeted an October release for OS X Mavericks and with the Golden Master build now available for Mac developers, we expect a public release could be in the near future. There are reports suggesting that AppleCare staff are currently undergoing training which is expected to be completed by the 11th of October, so perhaps OS X Mavericks will see a release after that.
