Recently I updated my MacBook from Mavericks to Sierra and everything is going well… except the sync of my notes. I don't want to use iCloud sync because I don't want my notes on a foreign server. Yes, I am aware, that the new features are not supported by IMAP but I don't use them. I just use unformatted text.
What I have tried so far:
- disabling the account, reboot, an re-enabling it -> didn't work
- deleting ~/Library/Containers/com.apple.Notes -> didn't work
- following the description here: How to Sync Notes El Capitan to iOS 9 via IMAP -> didn't work
- searching the internet -> no further hints
How can I get this sync back to work?
