"Click" after 15" MBP Retina sleeps...???
Hi - I notice that when I return to my MBPr after it has been asleep (plugged into power) - that, if I wake it via the spacebar, for example - I often hear a "click" sound that almost sounds like an old fashioned camera click as it wakes up. Any thoughts/similar observations?
Thanks.
