The Mac FUSE based ext2/3 support is pretty unreliable IME. The Paragon software is kind of ok but $40.

If you're also using Windows then you'll need another commercial app.

Then the card won't work in TVs and other media players.

So, that's why I say they need to support exFAT. Yes, I know, it's money to Microsoft but presumably Jolla are already paying Microsoft for Exchange ActiveSync support* so I fail to see why we should get religious about it.


* which I really object to as they should have used IMAP/CalDAV/CardDAV ;-)
