Apple today seeded the third beta of OS X Yosemite to developers, almost a month after seeding the first OS X 10.10.3 betaand a week after releasing OS X 10.10.3 to public beta testers. The new beta, build 14D98g, is available for registered developers through the Software Update mechanism in the Mac App Store and through the Mac Dev Center. Apple has also released OS X Server 4.1 for developers. According to the release notes, today’s 10.10.3 beta includes developer APIs for the new Force Touch trackpad in the 13-inch Retina MacBook Pro and the upcoming Retina MacBook. OS X 10.10.3 brings several new features to Yosemite, including the new Photos for OS X app. Designed to integrate with iCloud Photo Library, Photos for OS X is a replacement for both iPhoto and Aperture and is on track to see an early 2015 public launch. Reviews have suggested that while Photos is a suitable replacement for iPhoto, with more advanced tools and performance optimizations, it may leave professional users disappointed. Along with the new Photos for OS X app, the first two OS X 10.10.3 betas introduced a redesigned emoji picker that consolidates emoji into a single page with clear labels, new diversified emoji and emoji skin tone modifiers, new flag emoji and updated emoji for the iPhone, iMac, and Apple Watch, and support for Google 2-step verification when setting up accounts in System Preferences.

Apple today made a pre-release version of OS X Yosemite 10.10.3 available to those who are signed up for the company’s OS X public beta program, giving them early access to the new update and the new Photos for OS X app. 
The public beta carries a build number of 14D87p, a slightly later build number than the 14D87h from the second developer beta of the software, released last week. 
All registered public beta test members should be able to download OS X Yosemite through the Mac App Store. 
OS X 10.10.3 includes access to the new Photos app, which is designed to serve as a replacement for Aperture and iPhoto. Early reviews have suggested the new software improves upon iPhoto, but leaves out many power features Aperture users have become accustomed to. 

Apple today seeded a sixth beta of OS X Yosemite 10.10.2 to developers, just a week after seeding the fifth beta of OS X 10.10.2, and two months after seeding the first beta.
The new beta, build 14C106a, is available through the Software Update mechanism in the Mac App Store and through the Mac Dev Center.
As with previous betas, Apple asks developers to focus testing on Wi-Fi, Mail, Bluetooth, and VoiceOver. Many Yosemite users have had some ongoing problems with Wi-Fi since the new OS was first launched in October, and a November 10.10.1 update did not resolve all of the lingering issues.
