Does WLAN support mean you can use Pi’s wifi? Have you tried transferring AppleShare over AppleTalk? I had some issues with Scuznet AppleShare over AppleTalk over wifi but never went back to try to sort it out.
Yes, and yes. AppleShare over AppleTalk (DDP) works perfectly over as long as your kernel has the appletalk module loaded. See the wiki page that I linked in my previous post above.
The one thing that doesn't work great, is using Netatalk in parallel with RaSCSI on the same Pi Zero W over an emulated DaynaPort network adapter on a slow Mac. If you try to copy files on the AppleShare over the emulated network interface, it will stall indefinitely on my SE. I think it is a Pi Zero performance bottleneck. A faster Pi handles this perfectly fine.
