As of today septmeber 30th 2013 the unity web player has become completely unusable on my Mac. Whenever I attempt to launch an application supporting it i get "error launching unity player" message.
I have tried using different browsers and uninstalling and reinstalling unity player over and over to no avail. I also get the same message when i try to view the unity cache.
I am using an Imac v10.5+ running safari (as said above also tried with different browsers). I have also come across other mac users having the same issues today.
Any advice would be greatly appreciated.
