I have submitted a support ticket but wanted to check to see if anybody else has noticed this. I installed the latest Evernote mac app from the app store onto my office iMac, running Yosemite. I log into the machine using a network account which mounts my home directory on an NFS share. Evernote worked perfectly fine until I rebooted the machine. Now when I try to launch it, it never opens at all and if I right-click on the dock icon it tells me application not responding and I do a force quit. I thought I fixed it a couple days ago, actually. I uninstalled the app and deleted the directories com.evernote* from ~/Library/Containers. Then, after another reboot, I reinstalled the app and it worked fine, until this morning. I came in, booted up my mac, and the same issue presented itself. I feel like this may have to do with the nature of my user account, because the ~/Library/Containers/com.evernote* directories are being mounted as a share, and deleting them is what fixes the problem, but I don't know enough about enterprise mac account management, mac apps, or Evernote to go any further than that. If anybody else has had any experience with this please let me know, and I'll update this when Evernote support responds.
