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.
