I was able to fix the crash on startup by following these steps from another thread:

  • Delete this folder: ~/Library/Containers/com.microsoft.onenote.mac
  • Delete this folder: ~/Library/Group\ Containers/UBF8T346G9.Office
  • Open up “Keychain Access” app on your Mac, and search for “MicrosoftOffice”. If OneNote recognized that you signed in, you will have an entry with a long name. Delete it.
  • Restart your computer.
  • Try launching OneNote and signing in again.

    I've been trawling the Internet trying to find an easy solution, because not all of us can follow/find the solution to this problem. The best solution I have found and am currently using is downloading an app called "Outline" from the app store. It will sync with your old onenote notebooks, so you don't loose your work. Plus it doesn't crash!

    Hope this was helpful.

    Hi Scott,

    Thanks for this! Great stuff.

    I had a OneNote crash on my iMac last week and managed to resolve following your steps. 

    Today I had the same crash (no idea what's causing it). I followed only your first line of instructions and it's now working fine as well.

    Just thought of sharing, because deleting the Keychain access entries caused all my email accounts to be removed from Microsoft Outlook.
