On February 23, Apple seeded the second beta for OS X 10.10.3 Yosemite to tester and developers, and now, several weeks later, the third beta (build: 14D98g) has been released.

OS X Yosemite 10.10.3 includes the all-new Photos app, which replaces Aperture and iPhoto. In both appearance and features, Photos for OS X is similar to the Photos app bundled in iOS. The two apps share the same approach to photo management with both versions featuring a robust organizer coupled with basic editing tools.

In addition to the Photos app, OS X 10.10.3 also includes a redesigned single-page emoji picker, along will all new emoji and emoji skin tone modifiers. It includes several new people emoji for greater diversity, and 32 new country flags to choose from, which includes flags for countries like Canada, India and others. Apple has also made some changes to better reflect its own products as well, supplanting the existing emoji for “computer” and “watch” with an iMac and Apple Watch, respectively. The emoji for an iPhone reflects an iPhone 6.

OS X Yosemite 10.10.3 also adds support for Google two-factor authentication.

OS X Yosemite 10.10.3 beta 3 is available to registered developers via software update in the Mac App Store. It’s also available through the developer portal on Apple’s official site.


9to5Mac reports that OS X Yosemite 10.10.3 beta 3 includes APIs for Force Touch feature for developers, which is available in the new 12-inch MacBook and 2015 13-inch MacBook Pro.

This beta of OS X 10.10.3 contains new developer APIs that work with the Force Touch trackpad in the new MacBook Pro (Retina, 13-inch, Early 2015) to allow a new level of interactivity and control within your apps.

Force click. Apps can have any button, control, or region on the screen respond to a press of stronger pressure. This Force click can provide a shortcut to additional functionality within the app.

Accelerators. Pressure sensitivity in the trackpad enables apps to give users greater control. For instance the fast-forward button in media playback can speed up as pressure increases.

Pressure sensitivity. Drawing and other creative apps can take advantage of the pressure-sensing capabilities of the trackpad to make lines thicker or give the brush a changing style.

Drag and Drop. Apps can add the springLoaded property to their controls so they can react to a Force click gesture while in the middle of performing a drag, for instance to immediately open a new target for the drop.
