Infinite Night Shift
Austin Johnsen (via Ashley Bischoff):
TIL that if you go North of the Arctic Circle in the summer and bring a MacBook with Night Shift set to be triggered by sunrise/sunset, the process will go into an infinite loop because the sun never sets...
I noticed this when my computer fan went crazy because my CPU was running at 120% trying to calculate when sunset was in order to trigger Night Shift. As soon as I turned Night Shift off, that process disappeared and the fan spun back down...

This is one of the first things I added to my unit tests when adding sun-based custom effect activation in Black Light Pro.
