Is there a way to stop the MobileMe synchronization from Terminal? It happens to me that, sometimes, the MobileMe synchronization starts when it should not, when Mac OS X is busy doing something time-consuming. In such cases, I try to stop the synchronization using its menu extra, but for some reasons the synchronization doesn't stop.
Is there a way to stop it from Terminal?
Try this :

sudo kill -9 /System/Library/PrivateFrameworks/DotMacSyncManager.framework/Versions/A/Resources/mobilemesyncclient


I don't use Mobile Me so cannot test this but this is the location of the Mobile Me sync command.  So killing it should stop the syncing.
