According to a report published recently by 9to5Mac, and citing the release of the fourth beta for OS X 10.10.4 Yosemite which took place earlier today, Apple is dropping the “discoveryd” and opting to go back to the old way of doing things, before the launch of Yosemite.
For those that didn’t suffer the issues, many Yosemite users complained of several different Wi-Fi issues, ranging from duplicate names popping up in the available Wi-Fi access points list, or even simply causing the Wi-Fi connection to crash unexpectedly. While developers and users have been complaining about these issues for quite some time, it took Apple to finally implement a fix.
That fix will reportedly find its way to machines out in the wild with the public release of OS X 10.10.4, which could happen in the near future. With that release, Apple will go back to the mDNSResponder method of handling network connections, which Apple used before the launch of Yosemite. That method didn’t see this sort of widespread problems, so it will be a welcomed return to the norm for many Yosemite users.
