SyncServer Unexpectedly Quit (resolved)

I believe that I have finally resolved the problem on my MacBook when starting that it would display this error message “SyncServer has unexpectedly quit” with a relaunch button.

After doing a few google searches I found a site that referenced this problem a way to resolve it.

Since, I wasn’t using .Mac for anything the solution was to:
1) Delete the following folder: /Users//Library/Application Support/SyncServices/
2) Reboot

  1. Thank you! I had this issue start earlier today and found that my Mac was running slower than usual. Deleted the folder (I don’t use .Mac at all) and all is well again 🙂

  2. Any idea if there’s any danger deleting the folder if you do use .Mac?

  3. From the Apple website:



    As if it were a swarm of bees, you should stay away from the SyncServices folder. Removing or modifying anything in the SyncServices folder–or in any subfolders within it–may cause unexpected issues. (This folder is located in your Application Support folder, in your Library folder, in your Home folder.) Deleting or modifying things in the SyncServices folder may cause unexpected results such as:

    * Duplicate contacts in Address Book or appointments in iCal.
    * Data loss in Address Book or iCal.

    Important: Any lost or duplicate data could propagate to other devices and computers via iSync and MobileMe sync. This means data could be lost on other computers.”

    O would not touch it

  4. It would seem to me that the big ominous warning on Apple’s site is referring to problems that could occur if you use MobileMe… and I agree, this is true. However, since both Jeremy and Matthew claimed to not be using .Mac or MobileMe at all, I think this is a safe move.

    I just used this trick on a client’s iMac…. it was running very slow and crashing periodically with an error message that said, ‘SyncServer unexpectedly quit’, around the same time every day… since they are not using MobileMe, I deleted this folder. I will check back tomorrow to see if there has been an improvement.

    For those who experience this problem but do use MobileMe, try reseting sync services first…

  5. I get the same error message but when I tried to delete the SynchServer folder as instructed above, it is nowhere to be found on my computer. I cannot even find it if I search for it. How am I getting this error message then?
