Home sharing on iTunes 11.0.4 is keeping my mac awake...help?!

Hi All.

 

After upgrading iTunes to 11.0.4 my faithful Mac mini can't get any sleep. It tries, but as soon as it sleeps something wakes it back up again within seconds. Actually what happens is the mac sleeps then about a minute later it wakes for a few seconds and then sleeps again, another minute later and the cycle repeats.

 

So far i've narrowed it down to iTunes and then to home sharing. If i quit iTunes or disable home sharing the Mac Mini sleeps fine and stays asleep. Load iTunes with home sharing turned on and it's back to its insomnia.

 

Now i'm not all that clever when it comes to the reading console logs or tinkering in the terminal, but i did manage to confirm this with 'pmset -g assertions' and watching the state of  'PreventUserIdleSystemSleep' change from 1 to 0 and back again as homesharing was turned on and off - it's all fun!

 

Does anyone have any suggestions or is this something common to 11.0.4? It worked fine before the upgrade.

 

I have a macbook air which i'm going to have a play with tonight and see if i can replicate the problem there, but if not i'll need help working out how to fix it on the Mac Mini. Hosting my iTunes library is all it has to do in life, without home sharing life has no meaning for it.

 

Many thanks in advance.

Mac mini (Mid 2011), OS X Mountain Lion (10.8.2)

    Hello ScutterOz,

     

     

    This behavior is to be expected, as the system must maintain its presence on the network in order for other devices to be able to locate your Home Share.

     

    About Wake on Demand and Bonjour Sleep Proxy

    http://support.apple.com/kb/HT3774

     

    With Wake on Demand enabled (see below) and your Mac in sleep mode, your Mac will occasionally wake for a brief time, without lighting the screen, in order to maintain active shared service registrations with the Bonjour Sleep Proxy. On some Macs, sounds from the optical drive, hard drive, or fans may be heard during these brief periods. Note: Removing a sleeping Mac from the network will automatically remove its registered shared services from the Bonjour Sleep Proxy.

     

     

    Cheers,

    Allen
