Apple released a new OS X 10.10.4 beta for the developers as well as public beta testers, exactly one week back Apple had launched their fifth OS X 10.10.4 beta and also launched first OS X 10.11.EI capitan. The latest new OS X 10.10.4 beta carries the build number 14E36b and is available through the Mac App Store and Mac Developer Center.
The previous version OS X 10.10.3 brought many consumer facing changes including the new Photos for OS X app, a redesigned emoji picker, and diversified emoji, but OS X 10.10.4 appears to be an under-the-hood update that brings performance enhancements along with bug fixes.
All the beta versions of OS X 10.10.4 have not included outward facing design changes or feature additions, where as the latest fourth beta which was released few weeks before came up with significant behind scenes which will improve the networking performance for the users who have experienced the issues with OS X Yosemite.
There is no any announcement from the company that when Apple plans to release OS X 10.10.4 to the public, but the fact that we’ve now received six betas suggests we may be nearing the end of the beta testing period. It’s possible we could see the public release of OS X 10.10.4 on June 30, the same day Apple plans to release iOS 8.4 with the new Music app and Apple Music service.
