SOLVED: discoveryd eating up battery and CPU on Mac OS X Yosemite 10.10.3
Raw
gistfile1.txt
discoveryd is completely fucked in some way in Yosemite. It randomly starts using up 100% CPU and doesn't stop until you reboot or the laptop dies.
To fix the CPU/battery rape, you need to restart the service with these shell commands:
launchctl unload -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
launchctl load -w /System/Library/LaunchDaemons/com.apple.discoveryd.plist
No sudo required. The problem will randomly return after restarting the service, so I configured launchd to run a shell script with those commands in it every hour.
No more problems, and it appears to have caused no side effects.
