I just upgraded to MacOS 10.13.4 High Sierra. I am now getting this "Not Secure" message in the URL window of Safari. I also upgraded OctoPrint to 1.3.7rc4 on the same day so I am not sure who is causing this or what it really means. I would tend to blame Apple before Gina!
Has anyone else seen this?
OctoPrint 1.3.7rc4 running on OctoPi 0.14.0
