Mac OS X: Do not remove or modify the SyncServices folder
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. This means data could be lost on other computers.
If you are attempting to troubleshoot an issue that involves this folder in Mac OS X v10.5.x or later, see this article.
