If your Mac is a 2012 or older model, it probably does not support this feature. You can check the wording of the Wake for Network Access checkbox in Energy Saver settings. It will read 'Wake for Wi-Fi Network Access' if your Mac supports this feature. After upgrading to sierra, it looks like the feature 'Wake for network. When the “Wake for network access” checkbox is selected, your Mac wakes at the. You connecting ( screen sharing ) two Macs on the same wifi network. ![]() I've upgraded to Lion and everything's fine apart from one problem: using my iPad to access home shared iTunes content on my mac no longer works when my mac is asleep. That's a change in behaviour from Snow Leopard; I used to be able to sleep my mac and then wake it over wifi using either my iPad or iPhone to access all of my home shared libraries. The mac screen used to light up for ten seconds and then go dark again, but it served me the files. Lion seems to go into a deeper sleep which it can't be woken from. If I attempt to wake my mac from my iPad within about ten minutes of putting my mac to sleep then home sharing seems to work and lets me use the home share libraries, but if I leave it any longer than that then the mac seems to fall into a coma and can't be woken. The weird thing is that I still see a 'shared library' folder on my iPad, but when I click on it nothing happens. I think my Time Capsule is listening for wifi access and issuing the magic packet to the mac, but the mac just ain't listening. I'm using a Time Capsule in bridge mode from an ADSL modem and I've accepted a TC firmware update last week and I'm on lion 10.7.3. I've tried using Ethernet to connect the mac to the TC (and temporarily disabled the wifi connection) but that still doesn't work. Also, note I'm NOT suffering from the problem that 10.7.3 seems to be giving a few other people - my mac reconnects to my wifi just fine when I wake it up manually. For the record, This was an upgrade, so there's still a tick in 'wake on network' in power settings and home sharing on iTunes is still configured the same as it was before. ![]() Does anyone have any suggestions about how I can get home sharing to work when my Lion mac is asleep please? Did you update to 10.7.3 by the Software Update, or did you use the Combo Update? If you did it with Software Update you should reinstall with the Combo Update. If you did it with the Combo Update make sure that you used the Combo Update that came available a few days later than the first Combo Updater. That solves a lot of possible issues already. I guess doing the following can do it too, when you did the above correctly: uncheck 'wake for network access' in Energy Saver, restart, then check it again and restart.

It does not mean wide area bonjour, to access services from the internet. So Bonjour sleep proxy server is the technical part, that allow Wake on demand and is provided by Time Capsule and Airport Extreme. I did the delta update and I also tried to install the combo update and I even reinstalled from the Recovery HD. The problem still existed after all that: Wake on demand stopped working. But I think I got it solved by a solution I found here: I replaced the IO80211.kext againt an old one from snow leopard. Now it seems to work fine, but Airdrop (new feature from lion) is not working anymore, because this feature was not supported by the old driver. But I do not need Airdrop, but wake-on-demand. I use Wake-on-Demand to wake up my mac from either my AppleTV2 or from apart, if accesing its ressources via the 'Back-to-my-mac' feature or to access EyeTV. So Wake-on-Demand is very important for me.
