My iPhone 4 (iOS 6) has stopped syncing wirelessly (with my Mac) over the course of the past few weeks. When I connect it via the cable, iPhoto pops up and I can get the photos off, but it doesn't start syncing the music / apps automatically. I have to hit the "sync" button, and even then, it doesn't appear to be pulling the "last played" data off the phone.

The checkbox for "Open iTunes when this iPhone is connected" is checked, as is "Sync this iPhone wirelessly", and the "Sync Music" stuff... I haven't done anything over there. I've restarted the iPhone several times, did a restore after 6.0.1 came out, and am considering reinstalling iTunes on the Mac (though I'm not even sure that's easy or possible).

What might be stopping the sync from being effective?

Happens all the time to me. Wireless syncing seems highly sporadic. I know it's supposed to kick off when on wifi, the computer iTunes is available, and you plug it in, but those conditions are true for me all the time and it seldom works. I just make sure to plug it in and click sync. I've updated, reset, etc, nothing seems to work properly. – Alex Nov 8 '12 at 4:27

iTunes uses to detect if an iPhone has been plugged in. This app is usually started as a login item. Therefore you could check if ist listed here: Preferences -> Users -> Login Items. If it's not listed you can drag it back as described here:

I'll check that out. Thanks. – dnord Nov 8 '12 at 14:09
I found, but it had a tiny yellow triangle by it. I removed it and added it (from the iTunes package) and it's been smooth sailing. Whatever was in Login Items was definitely not right. Thanks! – dnord Nov 9 '12 at 0:24
