Mac wakes every 2 hours. what happened to discoveryd?

When I first installed Yosemite I found that my iMac would wake itself up every 2 hours, stay awake for a few minutes, and then go back to sleep. I found with some googling that this problem was related to the /System/Library/LaunchAgents/com.apple.discoveryd launch agent. I used Sleepwatcher to have that launch agent automatically unloaded at sleep time. Hooray, no more every-2-hour-wakes. http://apple.stackexchange.com/questions/151568/mac-wakes-up-from-sleep-every-tw o-hours-on-mac-os-x-yosemite

After installing 10.10.5, though, my Mac is once again waking every two hours, and the /System/Library/LaunchAgents/com.apple.discoveryd file is missing. Anyone know what launch agent or other process is now responsible for the every-2-hour wakes, so that I can unload it instead?

iMac, OS X Yosemite (10.10), iMac (Late 2009), 3.06GHz

As it was too buggy, Apple dropped discoveryd and has reverted to what it used before (mdnsresponder).

discoveryd has been removed in favour of the older mdnsresponder. You can probably find details if you search around, many sites discussed it.

I'm assuming you have tried all the regular 'disable network wake' settings etc?

mDNSResponder. With OS X 10.10.4 update, Apple has replaced discoveryd and brought mDNSResponder back (back as it was used in previous OS X versions).
