killall SyncServer
Then, press return. You may get a 'no such process' response. That's okay. That just means that SyncServer wasn't running when we told it to stop.

Next, enter the following command into Terminal and press Return again:
rm -rf ~/Library/Application\ Support/SyncServices/*

FYI - I was having same nightmare with OF not syncing (OF->iCal only it was syncing from iCal back to OF). Did the above and it synced first time AND was really much faster!

Thanks for the fix.
