Roughly two weeks after releasing the second developer beta of OS X 10.9.1 to members of their Mac Developer Program, Apple has already seeded a third 10.9.1 beta. The update bears a build number of 13B40 – 5 builds newer than the previous seed. As with the previous betas, Apple continues to focus on Mail, Graphics Drivers, VoiceOver, and Shared Links while testing the update.
The update is available now through Software Update for developers using the previous beta. It may also be necessary to download Apple’s “seed configuration tool” (also available in the developer center) before being able to install the update. As usual, we’ll let you know if we spot anything interesting!
