Kobo Aura is now mounting as a FAT share on macOS Big Sur and Calibre doesn't work

MelBr · 11-23-2021, 03:32 PM

Hi all,

My father has complained to me that his Kobo Aura doesn't work with Calibre anymore. I've noticed that macOS now mounts his Aura as a FAT share on his computer and doesn't use MTP anymore. As a result, Calibre doesn't see it. A workaround I found for him was to use the "Save" functionality but that's not as convenient and intuitive as "send to device".

Does anyone know why this has happened? Anything we can do? Can calibre support this new mounting system?

Kobo version is: 4.30.18838

Thank you.

Kobo e-ink based ereaders such as the Aura run Linux and have never mounted as MTP. The should be mounted as a USB MSD. Or whatever the MAC calls that. There have been issues with new MACs, due to changes in how they work. I believe they have been sorted out, but, don't know enough to tell you what they are.

But, a starting point is to do what is in https://www.mobileread.com/forums/sh...d.php?t=118560. Posting the results of the last step will let us see what calibre is actually seeing connected to the device.
