Virus or Hack
I recently bought a 24" iMac, and retired my old 2013 iMac as it was not supported by Apple. I thought there may have been a virus or hack on the old Mac. Thought that if I turned off wifi and the internet, my grandson could use it to play games that we put onto the computer for him. On my new Mac, the other morning, I opened my email and over 6000 emails started to download. I shut down but it said 10 emails had downloaded. Today my Mac seems to be glitching. I checked my old Mac and found it still on. I shut it off and checked the new machine and it seems to have stopped downloading these emails. But could something get into my new mac and how do I check?
iMac 24″, macOS 13.4
