I have been getting back into using Unity 3D, which I believe is a very useful and insightful tool, but I have been having trouble getting the Web Player to work. For some reason, when I would install it, Safari wouldn’t recognize that it was installed, even after restarting Safari.
Turns out that when the web player was being installed, it was being installed in the Unused Folder inside the plugins directory. So to fix it was as simple as moving it up a directory. Huh, funny bug.
