Apple today seeded the second beta of OS X 10.10.2 Yosemite to developers, two weeks after seeing the first 10.10.2 beta and two and a half weeks after releasing OS X 10.10.1 to the public.

The new beta, build 14C78c, is available through the Software Update mechanism in the Mac App Store and should be available in the Mac Dev Center soon.

Like OS X 10.10.1, as a minor update, OS X 10.10.2 is likely to bring bug fixes and performance improvements to the operating system. OS X 10.10.1 introduced several reliability enhancements, including improvements to Wi-Fi, but many users have still been reporting issues with Wi-Fi stability in Yosemite.

In the release notes for the second 10.10.2 beta, Apple asks developers to focus on Wi-Fi, indicating the update may fix some of the lingering Wi-Fi problems.
