jjj - I had the same problem. I eventually followed some of the advice on here, and deleted the version 6.0 downloaded via the App Store and did a fresh download (of version 6.0.1) directly from the Evernote website. That seems to have solved the problem for me. May not be the best solution, but it works.
Hi, the text in all my notes aren't visible. I just upgraded to Evernote 6.0 (not running on Yosemite), and this is what I see: https://drive.google.com/file/d/0B194GEcfmQXJWHRyN3VWYWNCTEU/view?usp=sharing It's all empty on the right-side. I'm not sure how to view the content.
