Just received my Mod Duo today. I’ve powered it up and browsed the menus but am unable to connect via my MacBook to the 192.168.51.1 address when connected via USB.
I was able to connect in restore mode and update to the latest version (modduo-v1.5.0.524.tar) and it seems to have updated as it’s supposed to. It rebooted and via the menu i see that version. I used the same MacBook to transfer the file over via USB.
Mac OS 10.12.6
Tested connecting with two windows machines (Win7 and Win10) and both connected flawlessly.
