iTunes not Syncing

Thanks for posting, it worked for me also. I am still going to check at the store and see if they know anything. I find it odd that it happen to a group all at the some time.

Dennis, please post your exact steps for resolving your problem using the "reset sync history" in isync.
Thanks

I agree. I'm interested in knowing what happened because i was able to sync with Leopard a week and a half ago but only when I tried last night I came across this issue. There must have been some automatic update that created some kind of conflict.

Just like the automatic security update a year ago made my old wireless router useless forcing me to buy an Apple router. (still no fix for old linksys routers fyi...)

Funny I browsed this whole post trying figure which thing i should do.
I woke this morning to sync my iphone before work and to put new music on it and it was stuck.

So... I did the easiest idea and it WORKED.

Just turn off airport...
and itll work

just like that.
Have a good day.

Don't waste time trying to reset your iSync files or changing any settings. It's a problem at Apple's end.

I turned off my Internet connection, and the iPhone synced without any issues, just like it would normally. The moment I turned on the Internet connection, it wouldn't sync again.

So many people can't possible all mess up their system/backup files at the same time.

Hope that helps.

I've found something that works for me repeatedly: The problem exists when the iPhone is connected to the USB port, when iTunes is not already opened, i.e. iTunes opens, as auto sync is ticked, but the sync hangs up. What I did was to force a quit of iTunes, leaving the iPhone connected, and then restarted iTunes, whereupon the sync works fine.

This is very strange as I've been syncing the first way since I got the phone, with no problems, until yesterday, Dec. 27, when the problem started, for me, and for everyone else it seems. What on earth could this suddenly be due to? Have Apple changed something, and if so, how could this affect the syncing process when I'm using a version of iTunes I downloaded on Nov 10, and haven't reinstalled since then?

ya... it happened again

you can uncheck stuff and sync it fine once... but the next time you want to it wont work.

has anyone else had this problem? Is there a solution that fixes it for ever... this has never happened to me before i used a different ipod (nano) to move songs from a pc to the new mac.

Just tried this and yes it syncs fine without the internet connection; hangs up with the internet connection. Makes you wonder how much trouble the Apple guys take when changing something at their end?

I'm glad turning off Airport worked for you, but it does nothing for me. I've even tried syncing with the phone in airplane-mode... no difference.

I should also mention my problem is on a Windows XP PC, so I don't know if there is a "sycn history" to reset like some people have done.

the fix i posted above (just unchecking iCal only once and then rechecking it) has fixed it completely, for me at least. with and without an internet connection.

it may have been an arbitrary fix, not sure. but i have tried synching several times since and it works great now.

This worked for me too... for now

only time will tell TY

I experienced the syncing problem even though I've never had iCal checked...

then you may need to reset synch settings and check ical, sync it, then uncheck ical (if it hangs you may need to force quit before synching again)

Thanks, but I don't use iCal. I doubt it is iCal's problem anyway, as Windows iTunes users are also having the same problem, and they obviously don't have iCal.

Think I'll stick to my methods for now: either disable the internet (as suggested by someone else), or start iTunes manually when iPhone is connected to the Mac.

I could not sync this morning for the first time since I got the phone. I disabled airport (on my mac, not on the iphone btw), force-quit iTunes, and restarted. Nothing more, nothing less, and it synced when I re-opened iTunes. As soon as the sync started, I turned airport on and it continued to sync fine. Something must have changed - this is too much of a coincidence. I see a security update that my mac wants to install, but I haven't yet - I don't think I've had any other recent updates.
