“Apple today released OS X Yosemite 10.10.4, an under-the-hood update that introduces several bug fixes and performance improvements,” Juli Clover reports for MacRumors. “Most notably, 10.10.4 includes the removal of the problematic Discoveryd process, which has caused multiple networking issues for some users in OS X Yosemite.

“Discoveryd is a networking process that was introduced in Yosemite to replace mDNSresponder, but it caused problems like slow wake from sleep, failures to resolve DNS names, duplicate machine names, WiFi disconnects, excessive CPU usage, battery drain, and more,” Clover reports. “In 10.10.4, discoveryd has been replaced with the older mDNSresponder process.”

MacDailyNews Take: Finally!

Apple releases OS X Yosemite 10.10.4 – June 30, 2015
Yes, the fix for OS X Yosemite’s Wi-Fi problems is finally on the way! – June 12, 2015

  1. Mine did… Had to open Netwrok Diagnostics all the time to fix issues and finally get connectivity. Using the world’s ‘best’ laptop charged with the latest version of the world’s ‘best’ OS. Timmy, Timmy, Timmy… Will be adding this one to the list of embarrassing disasters on your watch. Steve would’ve eaten the programmers’ hearts for breakfast while handing pink slips and F-Off’s to those in charge. But it’s a different Apple now… a gentler Apple (watches, credit cards on your phone, buying a fashion headphone company instead of a great technological headphone company, hiring fashion CEO’s as VP’s, Gay Pride marching, etc.).
