iMac awakes after 2 hours. I have 'wait for network' unchecked. Went to logs and it said Wake reason: RTC (Alarm) In Mavericks, my iMac stayed asleep all night. Is there something else I need to check or do?
iMac, OS X Yosemite (10.10)
I've got the exact same problem as you. Since upgrading to Yosemite, my Mac wakes every two hours. And I've got the exact same reason given in Console.
Hi, SkyLilly, I had the same, and I have found this temporary solution but there is a little trouble đ
type in the terminal:
sudo /usr/libexec/PlistBuddy-c "Add :ProgramArguments: string --no-multicast"/System/Library/LaunchDaemons/com.apple.discoveryd.plist
then reboot your Mac. If something went wrong, you can revert with:
sudo /usr/libexec/PlistBuddy-c Revert/System/Library/LaunchDaemons/com.apple.discoveryd.plist
Connect wi-fi in System Prefs or Menu bar and choose your wi-fi network again. The little trouble I mentioned is that you don't see the power strength of your wi-fi in the menu bar, will be shown as disconnected, but actually is not.
Please let me know if worked for you also!
Thank you but no, not going to do that. I'll continue to power down at night. I want to see my power strength and should't have to break that in order to fix the sleep problem.
Exact same issue here with 2011 iMac, very frustrating. Apple really need to get their act together, can't believe this was ever missed..
As of December 15, I still have this same problem (on my vintage 2010 iMac). Is anyone aware of a solution?
I explained how I did above in this thread. For me working nicely and I didn't have anymore. Success
10.10.2 update solved this problem
Since Yosemite, iMac won't stay asleep
