Where do I find MacOS graphics drivers? I have a Mac Mini running MacOS 10.13.6, with an Intel HD Graphics 3000 384 MB graphics card. Google Chrome isn't recognizing the graphics drivers as usable for WebGL. See: 
WebGL disabled or unavailable on Chrome / MacOS 

According to Google, I should update my graphics card drivers. I can't find MacOS-compatible drivers on Intel's site: https://downloadcenter.intel.com/product/81500 How do I update graphics drivers on MacOS?
