Can I force sync *to* iCloud? All contacts delete themselves.
In MobileMe, you could force a sync in the direction you needed, but I don't see any way of doing that with iCloud.
For some reason, the first problem was that if any contact was in a group, that contact disappeared. But I have a backup made with the Address Book export feature. (I make a backup every couple of days. I distrust syncing where I can't force the direction.) I deleted all my contacts on the Mac, imported the backup, and everything including contacts groups is back to normal ... but only for about 20 seconds. During that few seconds where the Mac's Address Book is empty, the iCloud address book emptied itself as well.
Since the Contacts at iCloud is also empty, it appears that the syncing mechanism assumes that iCloud is correct, and deletes everything on my Mac and iPhone.
One solution *might* be to disable iCloud, turn MobileMe back on, import contacts, then sync upward to MobileMe. Then, switch back over to iCloud. But before I try that, does anyone know of a more elegant solution that forces my Mac to be the base data and force an upload to iCloud?
