OS X 10.10.4 Beta 4 Released for Testing
Apple has released a new version of OS X 10.10.4 beta for those participating in the OS X Yosemite Public Beta program, and for registered Mac Developers. The new build arrives as 14E26a and aims to “improve the stability, compatibility, and security of your Mac”.
The download itself weighs in around 1GB and, as usual, users will need to reboot their Mac to complete the installation.
The new beta build mentions a focus on Photos app and Migration assistant. There are no obvious changes or new features introduced to OS X 10.10.4, suggesting that the future OS X Yosemite update could be aimed at resolving bug fixes, stability and performance changes, or various other under-the-hood adjustments.
One notable change in the new beta is that discoveryd has been replaced with the old fashioned mDNSResponder, as noticed by 9to5mac. This could be in response to many of the ongoing networking issues that have plagued some OS X Yosemite users, ranging from failing wi-fi connections, to problematic networking discovery, Bluetooth discovery issues, amongst other connection related difficulties in existing OS X 10.10.x releases. It’s unclear if OS X 10.10.4 will resolve those issues, and impacted users will have to wait until the final version arrives before knowing for sure.
No known timeline for OS X 10.10.4 exists, but there has been some suggestion the final public version could be unveiled around WWDC 2015, which starts in early June. Apple typically goes through multiple beta builds before releasing the final version to the public.
