"App Nap" should not be a problem since 2 years (Software v7.1.5), so we assume you have a problem with V8 that you do not have with V7.
Can you please send us your V8 Lightshow and explain how to reproduce the "crash" you are talking about :
viewtopic.php?f=3&t=168viewtopic.php?f=3&t=19Please can you answer the following questions :
- What happened when the software "crashed" ? (Freeze ? Error message from the OS ? If yes, what message ?)
- What is the Mac OS version used ? (El Capitan if we right understood)
- What where you doing on the software when it "crashed", or at least what was the software doing when it happened ?
- How did you solve the problem ? (Restart the software ? Restart the interface ? Restart the computer ? ...)
Kind regards.
