Running a macbook air. Need to use an app to allow the macbook to be closed without sleeping, but I don't want the macbook to be at risk of overheating (which seems unlikely for this scenario, and the time based sleep setting in Energy Saver still work and have been set to 10 minutes). My thought was to run another app alongside NoSleep to accomplish this task. googling and searching this forum didn't readily yield an answer. Insomniax was a little wonky on my 2012 macbook air running 10.7.4. As soon as it was plugged in and then unplugged again, I had to exit and then restart Insomniax.
