So I am trying to install the CS6 Master Collection on my new mac which is running Yosemite. It's replacing my old mac pro tower which was running Yosemite as well. Everything works except After Effects. When I try to start AE the icon says "Adobe After Effects Render Engine" and when I try to open it it crashes. Does anyone know why it won't work and is there a work around or a patch to get AE to work properly?
In addition to what Vinay said (which you need to do to run AE on that OS), you also need to launch the full version of AE and not just the render engine. Menus are disabled and Render Queue window is open in After Effects
