Wake reason: RTC (Alarm) - how to deactivate?

[rpaloalto]

I even removed my wifi chip since I don use it. Plus discounted my ethernet cable. Still get the wake from sleep at 2 hour intervals. I'm not about to swap launch daemons from 10.9 to 10.10 just yet. Hope Apple decides to fix this since it seem to only be affecting a some older macs.

Does apple have any way I can report this. The only way I see reporting bugs is with a developer account.

Standard way to report is right here.

I prefer https://bugreport.apple.com/ because they write back to you sometimes so you don't get the feeling your feedback goes nowhere. You need a free dev account for it.

What the hell is even that RTC Alarm anyway?

Real Time Clock. The Mac thinks it has to wake up to refresh the advertisement of shared services, unfortunately this happens on Macs which do not have Wake for network access enabled.

OK, friends… you can also have a look at this manual: http://www.insanelymac.com/forum/topic/300072-wake-reason-rtc-alarm-how-to-deactivate/?p=2080144

Was promising to fix the bloody issue. Didn't work for me at all from what I can see in the Console log, but you may have a better luck than me.

Hello guys:
my Yosemite works fine on my laptop(Acer V3-571g).
My problem is that Yosemite wakes up automatically roughly every 2 hours for 10 minutes and then goes back to sleep.
It sounds like the PowerNap feature, but I have not activated that (it doesn't show up in Energy Saver preferences anyway).
I try to add Darkwake=0 in org.chameleon.Boot.plist of Chameleon r2391,but it doesn't work,so i try to reset my BIOS,and turn off "Wake From Lan",but it doesn't work.
Today I updated the DP6,but seems that apple don't fix this problem.

Do you have any clues how I can deactivate those RTC Alarm wakes?

Thanks!

PS: Sleep works fine in Mavericks without any RTC Alarm wake ups

As of 10.10.4, discoveryd has been abandoned for the old mDNSResponder. To fix the waking-up-every-two-hours issue now, try entering this in Terminal and then restarting your Mac:

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist ProgramArguments -array-add -DisableSleepProxyClient

This command modifies a system file and may need to be re-entered if Apple issues a software update that "fixes" this hack.

discoveryd is gone as of 10.10.4, and replaced with the old mDNSResponder. There's a new fix for the waking-every-2-hours problem. In Terminal, enter the following, enter your password, and then restart your Mac:

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist ProgramArguments -array-add -DisableSleepProxyClient

This command hacks a system file and may need to be re-entered if Apple issues a software update that "fixes" this hack.
