Why does the Note I shared via AirDrop to my Mac from my iPhone not show up in Notes.app?
The note will not show up in the Exchange account, but it will show up if you enable "On My Mac".
- Open "Preferences" in Notes.app
- Check the box next to "Enable the On My Mac account"
Now notes shared with your Mac via AirDrop will show up under "On My Mac". You can always copy these over to your Exchange account.
