iMac randomly restarts with frequent kernel panics
About 6 weeks ago, my iMac started randomly restarting multiple times a day. After logging back in, a kernel panic report followed. I'm very unfamiliar with the content of the report and what it means. The only thing I can think of around the time the problem started was when I added a new admin user account on my iMac which is very seldom used. I'm not saying that's the cause. I have since updated my OS to Sierra 10.12.6 hoping this would solve the problem. It did not. I'm also a Parallels 13 and a Windows 10 user. My Chrome browser is always open, as well as Parallels and Windows, when the restart suddenly happens. I've been using this iMac the same way daily for the past year with no problems until now. Even when my iMac is asleep, the restart randomly happens. Can anyone help me by viewing the latest report?
