I just updated Chrome to the latest version (Version 54.0.2840.59 (64-bit)) on macOS Sierra (10.11) and rendering seems to fail entirely. I don’t see any error messages.
I suspect this is a problem with Chrome, and not Cesium itself, I just wanted to note it to see if anyone else was experiencing this issue.
David, I just tried on my mac and Cesium loaded just fine. This is a mid-2011 mini with Sierra and the latest version of Chrome. (same one you posted). Anything in the console?
Does http://webglreport.com/ report success on your system after the update? I updated to Chrome 54 on my Windows 7 system with a 9800GT, and WebGL is now disabled globally. I suspected it might be a blacklist problem but updating to the latest NVidia drivers didn’t help.
I incorrectly reported that I was on macOS Sierra 10.11. I AM on Sierra, but it is, of course 10.12.
WebGLReport passes on WebGL1, but fails on WebGL2. Here’s my report:

I’m on a Late 2011 MacBook Pro with “dual” video cards, one of which is the Intel 3000, but it typically switches over to my AMD Radeon 6770 for OpenGL. (See above.) I can (and have) “forced” it to use the Radeon, and don’t see any difference.
The Intel 3000 on OSX does seem to be on that blacklist, but again, I can force the Radeon to be used, and do. Not sure if it’s still picking up that the Intel3000 is there, and still blacklisting.
There are no errors in the console, but it’s definitely something in the render loop, because I’m seeing it download resources (image tiles) as I “zoom in” with the scroll wheel. I just don’t get anything in the canvas.
I’m still experiencing this issue both locally (while developing my own app) as well as with the Cesium homepage and the Sandbox.
I’ve discovered that if I put a breakpoint immediately after creating my “Viewer” and allow it to break briefly, then continue, rendering seems to work out fine. I’d like to reproduce that in the Sandbox, but I can’t figure out how/where to break in there.
Is this some kind of a race? I can debug inside Cesium, but it’d be nice to have a hint where to start. Where’s the render loop begin?
