On 11/12/14 Most of my local data was not showing up on my Work Mac, my notebooks and notes where gone. I could see everything online. After trying to restore back-ups from Time Machine and my home Mac where I could see my data (before I connected it to the internet). I uninstalled Evernote and went to the Apple App Store and downloaded Evernote from there. When I synced again all my data was back on my work Mac. Just to see what would happen I synced my Home Mac and the data disappeared on it too. So I did the same thing to it and it is working fine now.
