Apple has just seeded the fourth OS X 10.10.3 Yosemite beta (build number: 14D105g) to developers, and the second public beta to testers.

The fourth OS X 10.10.3 Yosemite beta version comes less than a week after the release of the third OS X 10.10.3 Yosemite beta. Apple had seeded the first public beta version of OS X 10.10.3 Yosemite to beta testers couple of weeks back.

The fourth beta version seems to fix the problem that new 2015 Retina MacBook Pro and MacBook Air users were facing while trying to install it.

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. The fourth beta version also included APIs for Force Touch feature for developers.

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.
