Unable to import notebook from my desktop "MAC" I recently switched from a Windows PC to a MacBook Pro at my job. It's been extremely difficult to try and get my notebooks imported to onenote on my new mac. For someone reason, I don't see any feature that would allow me to import from my external drive/desktop. The only option I get is to import from onedrive but being that there are so many firewalls on the network, this makes it even more impossible. PLEASE HELP!!!
Onenote doesn't work in a same way that you have in Windows PC. You have to upload your .onenote to Onedrive from your Windows PC and you can access them from your Mac. 

So, "Share" your notebooks from OneNote for Windows to OneDrive — then OneNote for Mac will "see" them in OneDrive's Documents folder and sync them down to your Mac.
