That looks like the Catalina background picture. What MacOS are you running?

What Model-year Mac is this exactly?


By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners, Bit Torrent, or a VPN that you installed yourself. 


¿Have you installed anything like that?
