Google Maps doesn't work well at all on one of my Macs. In Safari, the 2D view works, but the 3D view doesn't work. In Chrome, the satellite tiles are all black (but the roads are visible). In Firefox, the satellite and roads are both black. It's the same (and most recent) version of all these browsers as my other Mac, where it works fine. How does one debug this? I've tried googling (ha) for every combination of words I can imagine. Google's tech support seems basically nonexistent, for their free services. Or I can just open Maps.app, and it always works. The data isn't as good but it's not terrible, and at least the basics work fine. I'm not a heavy maps user so that's good enough for me.
