Hi I have the same problem :

I use mac book pro 2010 with mac os sierra 10.12.5
Ibook 1.10
Kobo aura one
Calibre 2.85.1

First i download a free epub book on my mac
Then I try to download on calibre and I have this message :

Échec à ajouter le fichier /Users/gwenolalemeur/Desktop/livre kobo/Jamais plus.epub au livre : /Users/gwenolalemeur/Desktop/livre kobo/Jamais plus
Avec l'erreur :
Traceback (most recent call last):
  File "site-packages/calibre/gui2/add.py", line 430, in add_formats
  File "site-packages/calibre/db/cache.py", line 1385, in add_format

IOError: [Errno 21] Is a directory: u'/Users/gwenolalemeur/Desktop/livre kobo/Jamais plus.epub'

I undertand there is a problem with epub files download on mac.
