Of all the things I love about OS X and Tiger (and the list is great), I can't say I'm very fond of the syncing architecture. It's fairly lame damn it. I recently bought a .Mac membership ($99 annually) to take care of my email, web hosting, and syncing for multiple Macs. The only problem is that the syncing part is stynking. And considering I'm not getting what I paid for, it's really ticking me off!
.Mac Support has been working on my bookmark syncing problems since April 24, 2006--it's now May 15, 2006; their most recent response to my latest inquiry was:

So I've tried some other 'fixits' while I wait for their lightning-fast customer support; You can view the entire procedure here at the Apple Discussion forums. Here's my summary:
1. I unregistered all my computers via Sys Prefs.
2. I turned off sync via the web interface for Address Book and Bookmarks. Then I deleted all the Contacts and Bookmark (the generic Apple bookmarks) entries via the web interface.
3. I deleted all .Mac keychain entries from the Keychain app.
4. Deleted "PendingNotifications.plist" and "conflicts" via my /Library/Application Support/ directory. I left "clientdata" alone this time (I tried deleting it last time and it didn't do anything).
5. I reset my phone and resynced it via iSync. My calendars came across, but for some reason my contacts won't go over now (on the phone).
6. Before syncing with .Mac, I went to my iDisk and checked the Bookmark.xml file. It was still there at 84 KB. I could actually open it with BBEdit and see that it's still the generic Apple URLs. I couldn't delete the file though.
7. I went to Sys Prefs at the Sync tab and turned on just Bookmarks. It was already set to "Manually" sync. When given the option, I selected "Replace data on .Mac". It seemed to sync and gave the green check mark, but then it gave me the "There was a problem with the sync operation. .Mac login failed." message. I went ahead and resynced the bookmarks again without error this time.
8. I went back to mac.com and turned on bookmark syncing and selected merge. Now my bookmarks are completely empty again online - at least the generic Apple bookmarks are gone. I went to Sys Prefs and selected reset sync data to try again. The bookmark.xml file on my iDisk is now 1 KB in size.
9. So I went ahead and tried syncing everything else again. My online contacts will not sync now. Don't know why. I'm assuming this means nothing else is syncing.
So I lost my online contacts and my phone contacts--very important--more so than bookmarks on .Mac! So I found this online solution thanks to Josh Blander. I just deleted my entire ~/Library/Application Support/SyncServices directory and restarted. My phone was back and my .Mac contacts synced again after that. My bookmarks, however, were still in the toilet--no syncing permitted. I have no clue why they won't sync. They'll sync if I create a new OS X account and add a trial .Mac account. But not with my PAID account.
