I got webgl to work on safari, but can't get it to work on chrome. I use this to test
On safari, it works only after enabling webgl, see http://support.apple.com/kb/PH11926
On chrome, it says "Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card"
I was hoping there might be a way to enable webgl in chrome the way it's enabled in safari.
I am on Mac OS X 10.8.2, using Macbook pro retina (NVIDIA GeForce GT 650M), Chrome version 24.0.1312.57. My video card is not on a blacklist (but not on any whitelist, either) www.khronos.org/webgl/wiki/BlacklistsAndWhitelists
Enable "Use hardware acceleration when available" in the Chrome settings.
I had the same problem on a mid-2012 Macbook Air. Here's how I fixed it.
