I copied a version and tried to replace the currently working file with the version from TimeMachine, but when I did this and re-ran OneNote, the OneNote for Mac App icon returned to bouncing up and down, and had to be force quit, removed, then reinstalled. Next I tried to go into the Time Machine, back in time, and see the ~/Library/Containers/ files from different dates. I did, and OneNote worked, but none of my previously created folders appeared. The technician recommended I remove OneNote for Mac, and re-install. I spoke to a technician who said folders should be in the OneDrive cloud, but after checking the OneNote cloud, none of these folders where there. When the computer was returned, all of the programs worked, with the exception of OneNote, the One Note App icon bounced up and down and did not open. I took my iMac to a computer shop and got an upgrade to my hard drive. I was using OneNote for Mac, and created 30+ folders and content.
