I am having the problem as listed above, only after using Appcleaner to remove and then reinstall Evernote, it still crashes every time while migrating files! This is very frustrating as I use Evernote all the time and the web version is not the same!
Just installed Evernote 6.12.3 on my Mac running Yosemite 10.10. Evernote now unexpectedly quits immediately upon startup every time. I have uninstalled and reinstalled Evernote but the problem persists.
