On Tuesday, June 30, Apple officially released iOS 8.4 along with Apple Music, the company’s effort to jump into the music streaming business. But, the company also released an update for OS X as well.
OS X 10.10.4 is an update that is meant to work behind the scenes and improve overall usage for users, rather than unload a ton of new features. Specifically, for anyone that has networking issues with their Yosemite-based machines, this update should fix that thanks to the removal of the troubling “discoveryd” process.
Apple introduced the aforementioned “discoveryd” process with the launch of OS X Yosemite, and since then many users have complained of networking issues, ever since the new process replaced the old “mDNSresponder.” Of the many issues that users posted out, it included slow wake times, excessive CPU usage, a significant drain on the battery, unexpected Wi-Fi disconnects, and more.
With the release of OS X 10.10.4, though, the old mDNSresponder has made a return, which will hopefully alleviate those issues for users.
OS X 10.10.4 is available now through the Mac App Store and the Updates tab.
