My iMac has frozen during a render on Adobe Media Encoder (which is rendering an After Effects project, I render this way because I like to continue working whilst rendering). The render has taken 60 hours so far, and only had 13 hours left, so the computer freezing was extremely frustrating. Does the application continue to work, i.e. render, in the background during my computer freeze? The freeze is one where the screen is completely unresponsive apart from the mouse cursor, which I can move around, but which does not interact with anything on screen. If applications continue to run during these freezes then I'll leave the computer for a day or so before performing a force shut down. Any help is much appreciated. Thanks.
