A week after offering developers and public beta testers a first release of OS X 10.10.1 Yosemite, the company has issued a smaller second beta with the same focus areas as the previous version. The new build, 14B23, again asks testers to focus on Wi-Fi, Exchange email accounts and tracking down bugs in Notification Center, just as with the first beta. Those who signed up for pre-release builds for the Yosemite public beta will also receive the 10.10.1 betas.
