Hello everybody, In my area there are frequent power outages. When the electricity is back my iMac won't turn on. It is connected to a UPS. The only solution I've found is to unplug it from the UPS, plug it into the main socket, switch the Mac on, switch it off and reconnect it to the UPS. This process is quite struggling since the UPS is hardly reachable and I have to repeat it a couple of times a week. The other devices connected to the UPS work fine after the outages. It seems the iMac adopts a kind of protection. Has this happened to you? Is there a way to avoid it?
