A game I play recently created a new online viewer for their game using Unity. I have a Mac PowerPC G4 running OS X 10.5.8 with 1.25 GHz, 1 MB L3 cache and 1 GB DDR SDRAM. I use both Safari and Firefox. Whenever I open up the browser to start the viewer, the loading bar under the Unity logo loads until it is full, then my computer subsequently crashes and I have to restart the whole thing. This happens under both Firefox and Safari. I've even tried uninstalling Unity and reinstalling it to get it to work but it still makes my computer lock up.
I've been corresponding with the admin of the game I play and trying to figure out what's going on. He says there's absolutely no reason for my computer to not be running the new viewer. Other Unity-created games work fine on my computer.
