I'm using AE CS6 off the Creative Cloud for the first time with Mountain Lion 10.8.3.
Previously I've been working in Lion with CS5. I do intensive, long renders and in the past, anytime the computer was actively processing, it would never put it's hard drive to sleep. But, this morning, with the new OS and sofware, I discovered the render had simply paused when the energy saver kicked in. The hard drive had stopped.
Obviously I can turn off the energy save setting, but is this a Mountain Lion bug? I really appreciated before that I could hit a 12 hour render, and then if I was elsewhere, I would know that the computer would go into sleep mode upon completion of the render. Trying to stay green.
This seems like a good question for Apple.
I've been using Mountain Lion for a very long time with CS6 and have not seen this except when I've switched out of AE to another app, then walked away. If I walk away from a render without switching apps or if I'm rendering from the Adobe Media Encoder I have not seen this behavior.
That's interesting Rick. I'll have to test that. so basically the rule would be, hit render and don't use the machine to check or work on anything else. Don't leave the AE window.
I'll have to figure out where to post this question for Apple.
