Hello folks. I recently purchased a cyber power(CyberPower CP1000AVRLCD Intelligent LCD Series UPS 1000VA 600W AVR Mini-Tower) to use with my new 27" i7 iMac. The other day I noticed a quirky little issue where I got a message for a brief second that my imac was running on battery power, but clearly the iMac was not. The tool bar never, nor did the ups, state that the power source had changed, but a pop up message did. It only happened once so far, up is there anything to be concerned about?
