I've got a problem with my Mac Pro 7,1. I've had it networked to my Mac Studio. I don't need it very often but recently I tried to login to it. Unsuccessful. On the screen it shows a Apple wireless mouse with an arrow pointing to the on switch, I guess. I haven't had or used one of those for many years. I have an analog mouse plugged into the USB port. No change. Then there's a picture of what looks like a laptop pointing the side. I don't know what it's trying to tell me. I plugged a keyboard into it. Nothing works. Is this toast? Bricked? When I boot it the apple logo comes on but instead of showing user and password it shows these icons. At least it's not the old dreaded sad Apple Face. Help.
