OS X 10.10.4 Beta 6 Released for Testing
Apple has released the sixth beta of OS X Yosemite 10.10.4 to Mac users who are participating in the developer and public beta programs.
The new build arrives versioned as 14E36b and is downloadable from the Mac App Store Updates function as usual, assuming the user is opted-in to receive beta software, or is currently running a prior beta version. Developers can also access the download through the Apple Developer Center.
OS X 10.10.4 seems to be primarily focused on bug fixes and resolving various issues impacting Macs with OS X Yosemite, with perhaps the most notable under-the-hood change being a return of mDNSResponder to replace the problematic discoveryd networking daemon. That adjustment could mean a resolution for lingering network difficulties that some OS X Yosemite users have continued to experience, despite multiple OS X 10.10.x releases aimed at addressing them.
Though Apple has not mentioned a specific timeline for OS X 10.10.4 to be made available to the public, typically the beta process goes through several releases before a final public version is distributed. Being the sixth beta build of 10.10.4 could suggest that OS X 10.10.4 will be available to all users sooner rather than later.
OS X Yosemite and further 10.10.x releases are likely in maintenance mode as focus shifts to the next major revision of OS X, named “El Capitan” and versioned as 10.11, which will be released later in the year during the fall.
