Tested on Mac OS X Sierra 10.12.5 with... no success

!
I have of course followed the README and removed config file and the shepherd folder
I have try to send coins but after 25 mins I'm still stucked on screen "Processing transaction... Note: it may take a few minutes to complete the transaction.".
I try again and wait during 2 hours without success
I have no error in API logs, only the handler which is waiting for the tx (loop API call):
Time: 26 May 2017 16:42:56
GUI Function: iguanaActiveHandle
HTTP: POST
URL: http://127.0.0.1:7778
A technical point: please show logs by starting at the end. I have more than 800 +calls, I don't want scroll every time at bottom. Scrollbar is hard to reach with the mouse (when the scrollbar has appear, everything is going well)
UX: When you have only one address on the KOMODO wallet, it's maybe better to pre-select the address by default instead of showing empty history/balance. And the second time, best is to keep the previous address opened (auto selected address based on user habits) -> but be careful about the storage of this feature, some user will want to be able to disable it.
