May 8, 2015 10:26 AM in response to BobHarrisby SuperSizeIt,Yes I have provided feedback at the Apple Product Feedback page. This probably explains this glaring issues with Yosemite Wake On Demand Fail.

Good, but the Feedback page is not as "In Your Face" as a bug report, but any information send back to Apple is better than nothing.

Jul 8, 2015 8:31 AM in response to BobHarrisby WZZZ,Bob, maybe you can help with this one. I only recently started using screen and file sharing, and what I discovered was with Wake on Network allowed, the Mini on this network was getting woken up every two hours with "Wake reason: RTC (Alarm)". Only for 20 seconds or so, but that adds up to over 4,000 unnecessary drive spinups and spindowns over the course of a year--not too great to do that to the drive. At Insanely Mac there's a huge thread about this issue, which, at least for them was solved by adding
<string>-DisableSleepProxyClient</string> to the mdnsresponder.plist at ProgramArguments.
On my 10.8, where I did the edit, it shows this way:
<key>ProgramArguments</key>
<array>
<string>/usr/sbin/mDNSResponder</string>
<string>-DisableSleepProxyClient</string>
<string>-launchd</string>
</array>Ok, that worked just fine, no more waking up every two hours, but I just discovered that Wake for Network got disabled along with these RTC wakeups, so can't screen or file share to a sleeping machine, only to one that is already awake. Have tried the Go>Connect to Server, WOL.app, WOL in Tomato at the router, and WakeMe.app. All no dice.
Curiously, at Insanely Mac, no one has reported this problem. Is it as simple as Wake for Network won't work if Sleep Proxy is disabled? Or could there be some kind of workaround, even with it disabled. As already mentioned, magic packets from various programs are not doling the job, so that's not a possible workaround.

Look at <http://hints.macworld.com/article.php?story=20100401103451497>
Not sure if this will help, but it does appear to explain the wake up every 2 hours reason.

Jul 9, 2015 5:46 AM in response to BobHarrisby WZZZ,I have installed sleepwatcher, but know nothing about writing a script that will prevent these damned RTC Wakeups (which I do understand) and still allow Wake for network, which would appear to be the solution. I've seen several suggestions for that in a few places, but I'm more confused than ever.
