Apple Event: May 7th at 7 am PT

Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

The red-yellow-green lights have all turned black. They're really not necessary but I kind of liked them. Anyone know how to bring them back??

The signal lights (red-yellow-green) on my 1Mac have all turned black. I am running OS X Yosemite. Any ideas on how to bring the colors back?

iMac (21.5-inch, Late 2013), OS X Yosemite (10.10.4)
