Hahaha, macOS has some issues but not those you talk about. I've heard every windows user complain about such problems - which are not if you accept the fact you are on another Os ant not windows - when starting to use mac. nice clickbait btw.
IOT guy here, I like node-red but never dare to run it on edge device to perform ops on critical infrastructure. what is the state of the project? prototype only or business ready?
(Node-RED project lead here) It is not at all limited to prototyping. There are an ever-growing number of companies incorporating Node-RED in their own products and services - you can see a list of some of them on the project homepage.
They span a wide range of industries and technology areas. Quite a few are industrial controller companies who include Node-RED on their commercially available edge devices.
