<p>Today, when using OneNote for Mac my MacBook Pro crashed. After rebooting, it told me OneNote had caused the crash. Now, everytime I open OneNote, the app crashed immediately.

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.

    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.
