I took my laptop to a cafe today, and duplicacy failed to authenticate it's license.
I've done some research and it appears macs get their hostname from the DHCP server... so as you travel from network to network your hostname will change... and this will cause duplicacy to fail!
I would suggest duplicacy be changed to use a stable name for the license, not one that changes based on DHCP.

The only reason Duplicacy checks the host name is that on Windows there isn't a reliable way to generate a unique, non-changing uuid. Therefore, the host name is used to verify the machine.
However, macOS can generate a reliable uuid so there isn't really a need to check the host name. I'll make this change for the next update.

It may also be that the host name is stable on windows, I'm not positive, but I think it is. It seems really stupid that the macs get this from DHCP!
Thanks for the adjustment in the next update, and for being so responsive to the issues I have been raising!
