Ben sez,

Adobe After Effects (the loving companion to any motion graphics pro) has been crippled by the new Quicktime DRM. When After Effects renders out an animation Quicktime throws up an error telling you that you do not have permission to view the Quicktime movie that you just created.

Here you are using a mac as your trusty creative tool and now it's telling you that you are not allowed to access something you just created.

Apple DRM bitch slaps the very creative pros who love their products.
