The light flashes amber I have a message that it may be overheating How do i fix this
The unit which is over 2 years is correctly configured but the green light does not appear, it continues to flash amber. I get a message saying it may be overheating. I have left it unconnected to cool down but that has not solved the problem. It continues to perform back ups. Is there a solution?
iMac, OS X Yosemite (10.10.5)
