I found file transfer working fine with 'Android File Transfer' or XNJB. No need for developer mode or ssh. Drawback is file transfer shows your home directory only (no Android directories I think).
The problem is the phone is detected as 'USB communications device class', so the Mac loads the com.apple.driver.AppleUSBCDC driver. The driver seems to claim device ownership. That's why libtmp can not open the device. Additionally the drivers AppleUSBCDCACMData and AppleUSBCDCECMData will be loaded when connecting the phone.
Check with 'sudo dmesg' and 'kextstat' the drivers loaded. Bottommost entries in 'kextstat' show recently loaded drivers. Just unload all 3 drivers:
$ sudo kextunload -b com.apple.driver.AppleUSBCDC
$ sudo kextunload -b com.apple.driver.AppleUSBCDCACMData
$ sudo kextunload -b com.apple.driver.AppleUSBCDCECMData
The next time you reconnect your phone these drivers will not be loaded unless you restarted your Mac.
libtmp works fine after unloading the drivers. Even without vendor and product id. Check with 'mtp-detect'. You will still get the 'UNKNOWN' device message, but no more connection error. Same for 'Android File Transfer' and XNJB.
Note: The screen should not be locked when transfering files.
The USB CDC drivers are provided by /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns. Not sure if it's safe to remove/rename the AppleUSBCDC.kext in said directory. Especially with /System/Library/Extensions/IOUSBFamily.kext being code signed.
Edit:
Playing with libusb on my mac I found these information for my Jolla:

With all these additional interfaces exposed by the Jolla phone, your Mac/Linux computer may load additional drivers claiming the interface, thusly libmtp (which is supposed to be used by Android File Transfer and XNJB) can not open the device. That's why you have to find and kill other applications having claimed the interface and unload some drivers.
Would be nice if we can make Sailfish OS to offer only the MTP interface for file transfer mode.
Would be nice get it working with iPhoto and iMovie without need to use Image Capture app on OS X. Getting access to other files would be nice too and preferably so that mounting a file system would be the solution. That would solve the iPhoto issue too.
Penguin ( 2013-12-24 22:30:26 +0200 )editThanks for all fine answers! Actually a ready-made solution is needed for accessing Jolla's files from Mac and other computers without developer mode. [Says somebody who has developed enough and only wants to use his device]
jpek-m ( 2014-02-03 21:42:32 +0200 )editI have to say I'm rather shocked this does not work. I knew I was going to lack the bliss of iCloud syncing everything, but not even showing up as a USB drive (like the N9)? Basically it seems there is no user-friendly way of hooking up the Jolla with a Mac. Really unfortunate considering how popular Macs are these days.
Setok ( 2014-02-17 00:25:03 +0200 )editWould be nice if USB Mass storage would be supported in addition to MTP.
avdwoude ( 2014-02-20 02:09:38 +0200 )editApparently the Jolla USB vendor/product IDs changed in the 1.0.4.20 update. When selecting "PC Connection" mode, the device comes up as 2931:0a05 now, but it used to be 2931:0a01. Only the latter was added to the development version of libmtp, so this might need yet another entry now.
