I've been waiting for a version of PC AutoSave to be available for Sierra and I noticed tonight that v1.0.1.0 is available. The note says "The compatibility with macOS Sierra is added". I am trying to link my XT-10 with PC AutoSave for the first time. I select 'PC Auto Save Setting' from the menu on the Mac app. I then select 'Manual Setting'. Then I navigate through the menu on the XT-10 to 'PC Auto Save Setting' and 'Manual Setup'. I choose my router SSID from the list on the XT-10 and then connect the camera to the router successfully. The camera then searches for the PC, finds it (same PC ID number shown on camera screen and in window for Mac app). The camera then asks if I want to "Register this destination?". I click OK and the camera screen displays 'Registering this destination'. So far so good. However at the same instant I press OK on the camera to register the destination, the Mac app just crashes. The camera is then left displaying 'Registering this destination', but never succeeds in doing so. I've redone this about a dozen times now and have also done a full Mac reboot, but I always get the same result. Any suggestions?
