Lol. Ahh I needed that laugh about the $15 bills. But seriously now! No time for silliness, I'm on a roll! It's either onion, or Kaiser, I'm not sure.
I prolly haven't used a Mac since the 80s, so I know nothing of the procedures thereon. So for any who aren't bilingual, you may need a translator. I have been watching the Processes in my Task Manager.
Take nothing I say as fact, except that of my own experiences. This is all just very strong belief at this point, but verging on knowledge as I continue narrowing it down.
Neither AMDS nor ATH is necessary for Home Sharing.
It has absolutely nothing to whatsoever to do with AMDS. Not saying that that needn't be started in order to sync, because it does, but I don't think this is the perp. Apple tells us to restart it in Control Panel\Admin Tools\Services. If its process is ended, then the sync buttons remained black, so I clicked one. After a couple errors AMDS restarted itself in Processes. But it only gets partially synced, then phone can't be found, but remains in sidebar and sidebar. Sync buttons seem to keep returning to black. But keep failing. Sometimes phone button grey, and iTunes button black, but sync always fails.
A separate process Of ATH.EXE runs for each iDevice that connects to PC. Not sure how exactly they are started. When I plug ipad mini into iTunes 10.6.3 ATH stills fires up a process, even though the mini needs 10.7 or later to sync at all. Sometimes after ATH stops, even cabling phone to PC still won't restart ATH, after which a relaunch of iTunes and a reconnection (in some manner) of iDevice seems to restart it.
What causes ATH to fail? I cannot find a way to restart it from PC. I think somehow ATH is started once iTunes realizes the iDevice is receiving power. Sometimes iTunes thinks power was lost, or that the iTunes eject button was clicked. So stops the ATH process, or at least makes it unusable until reestablished. Sometimes an iTunes relaunch restarts it, sometimes not.
10.6.3 seems to be way more stable, but hard to tell since I have been fiddling around with it. Curious what others have to say about how their ATH.EXEs are behaving with iTunes 11. Gonna leave iTunes running 24/7 like it usually is anyway, and see how things go for a while. It's 6am here, so going to bed. Let y'all know if it syncs in the morning, erm, I mean afternoon.
