As you might have heard, in a recent beta of OS X Yosemite, Apple appears to working towards addressing the spotty WiFi issues that OS X and iOS users have been experiencing for a while now. One of the changes they have made is by dropping the use of a piece of software called “discoveryd” and replacing it with “mDNSResponder” which was used in previous builds prior to Yosemite.
Well the good news is that apparently this change will stick. According to the folks at TheNextWeb, it seems that Apple has killed off discoveryd for good in the upcoming updates to OS X and iOS, so when OS X El Capitan and iOS 9 finally rolls out to the masses come this fall, your Mac computers and iOS devices should no longer run into any WiFi issues, at least not as far as the software is concerned.
This is great news although a little odd, given that prior to Yosemite, Mac computers had used the mDNSResponder tool so we’re not sure what was with the change. Presumably there were some added benefits to switching to discoveryd, but we suppose the issues that cropped up later were just too problematic for Apple to keep using it.
In the meantime OS X 10.10.4 beta has already dropped discoveryd so when it is released to OS X users, you guys should be able to get an idea of what OS X El Capitan will be like as far as WiFi issues are concerned.
