iPhone sync using iTunes gets stuck on step 3 of 7 syncing calendars

I am getting stuck on step 3 of 7 when syncing my iPhone 4 using iTunes. I have had this happen before with iOS5 but it seemed to sort itself out after I deleted the backup from iTunes 10 > Preferences > Devices > iPhone backup and synced again a couple of times. I recently installed iOS6 and the sync problem has come up again. Apps and contacts seem to backup fine. I have tried deleting the backup and a reset (by holding the sleep & home buttons down) but I still don't seem to be able to get past step 3 of 7 sycning calendars. I noticed that a few users seem to have this problem from time to time. Any help would be greatly appreciated.

iMac (21.5-inch Mid 2010), Mac OS X (10.6.8), Also older Macs

I am having similar problem. I used to reset my sync history in isync, but that does'nt seem to work. I keep getting stuck in calendar sync and it doesn't move past it. after about 30 minutes, I just cancel the sync, so other things aren't getting synced either. IOS 6 is a nightmare!

Thanks for the comments. After a number of attempts over a couple of weeks sync seemed to work and get past 3 of 7. It is a mystery to me because I didn't perform any resets or do an upgrades.


I have a fairly big calendar and can only think that sync might get stuck or time out sometimes. This could be more likely after an iOS upgrade when the intial syncs are going to take a bit longer. Once that is done the backup might only have to be incremental.

I had it hanging on Calendar sync as well ...


This worked for me:

I also had crazy dupes of calendar items previously except on my iphone, so the idea was to get the singular calendar of events synced back to my computer. So ...

I made sure Calendar was empty on my computer: ~/Library/Calendars/

Cleared out. Emptied Trash.


Then per above link, cleared sync services from terminal:

/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync .pl full


Plugged in iPhone, set my prefs again, sync'ed. Went thru the sync quickly and got everything back to normal with only single events.


The key here (on dupes) is to have at least ONE version of your calendar in good shape. And that may be thru your iphone backups.

(sorry I know I switched thread topics, but sync and dupes seem to go hand in hand)


Hope this helps.
