Can't wake Lion over wifi (or ethernet) using iPad and home sharing.

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?

Nope, me neither, I was wrong. With a slightly longer sleep, lion drops back into a coma and can't be roused by wake on demand. This is really rubbish, I pay top dollar for Apple kit and it works as advertised only briefly before the functionality is broken by an alleged upgrade.


I can see a pattern forming with all my Apple stuff - upgrades introduce lag or break 'cool' features and leave me needing to spend money again. I regret installing lion, but i was forced to in order to keep my stuff in sync with the demise of mobileme. I feel likeI'm always being manouvred into a position where i need to spend cash just to stand still with this company. Well, not this time. Apple; I know you're not listening, but you've just lost a switcher. I'm going back to PC's where things work, and where I had much more freedom to make my PC do what I wanted it to do (and where wake on LAN is trivial to achieve)


Take the Apple catchphrase 'it just works' and the apply a slightly different emphasis to the 'just' and its real meaning becomes clear.


Fanboys - don't bother.

Same problem here.

This is what —so far— I tried to do:


  • dump /Library/Preferences/SystemConfiguration/com.apple.PowerManagment.plist
  • originally upgraded to 10.7.3 with the Combo update revision B (for 10.7.3 upgrade release Apple did a mess with a first upgrade not working properly)


Next is gonna be nuking my system and re-install from scratch. Screensharing isn't working as well. My laptop battery is drained as **** since I've installed Lion on it.


Not happy and I'm starting to be really sick of spending too much time troubleshooting, it wasn't what I was used to do on my Apple stuff. It just worked.

Sorry, I don't seem to be able to remove the 'solved' status - if anyone knows how then please say and I'll do it.


In answer to your and Rayced questions/points:


1. I tried deleting PowerMmanagement.plist: didn't work

2. I'm on 10.7.3 combo update build 11D50b

3. I don't have Apple TV

4. I have a timecapsule (gen 3) in bridge mode connected by ethernet cable to a British Telecom ADSL modem (which has wifi disabled) and the TC runs all the wifi instead.

5. Back to my mac - not tried, I don't have a macbook

6. EyeTV - nope, not heard of it.

That only affects a bunch of models made in 2009. I don't think that's gonna solve this issue.

Meanwhile I've managed to get through it dumping (once again…) the preference file /Library/Preferences/SystemConfiguration/com.apple.PowerManagment.plist then let the system make it again by opening and editing the power managment pref pane. Now it works if I put to sleep mode the computer, I don't know yet if it's gonna work when the computwer goes automatically in sleep mode (I still have to test it) after the proper time I've set in the preferences.

Ok, i thought it has something to do with the ATV (also has an sleep proxy functionality) or EyeTV.


I searched a lot and i found something, that probably fixed it.

Not a solution, just a work around:



Edit File
/Library/Preferences/SystemConfiguration/com.apple.Boot.plist

 



<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><?xml version="1.0" encoding="UTF-8"?>
<plist version="1.0">
<dict>
        <key>Kernel</key>
        <string>mach_kernel</string>
        <key>Kernel Flags</key>
        <string>darkwake=0</string>
</dict>
</plist>


if you know to handle the vi editor you can use


sudo vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist


or use pico

sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
