here's an imac douzy of a problem
Bought a 2019 imac used from a reputable company. Started up fine. Upgraded it to Sequoia from Catalina. Now here's where I stand:
Started up normally with keyboard and mouse. Very slow even with catalina..
Started up again. Fan started blowing. Would not regcognize peripherals (keyboard & Mouse.)
Tried to start up and it died. Moved it to new area. Plugged it back in. Black. Held down the Power button. Nothing. Plugged it into my old computer. stilll nothing.
Any other ideas before I kick it to the curb???
iMac 21.5″, macOS 10.15
