Magento officially recommends Livereload for "watching" changes made via Grunt and updating the browser in real-time without reloading the page for each change here: https://devdocs.magento.com/guides/v2.4/frontend-dev-guide/css-topics/css_debug.html#add_theme
The problem is that Livereload has not been maintained and updated since 2015 and is basically unusable for me on OS X 10.15. For example the Chrome extension often falls into an infinite reloading loop which causes my browser to DOS my own server by sending an update request for the current page every second.
Can anybody recommend another app or workflow for live-updating the browser during Magento 2 development using Grunt as provided by Magento?
