Multiple kernel panics a day
My iMac has been shutting down 3-5x a day with kernel panic reports for over a year now. I have gone through the apple support and booted in safe mode, done a hard restart, run diagnostics, wiped the computer completely and reinstalled High Sierra OS to the same result. The problem happened with Yosemite and Sierra OS as well. Bringing it into an authorized repair shop ended with 'we could not replicate the problem and everything looks fine'.
Guess this is a last Hail Mary to see if anyone can help pinpoint this issue before moving on to a new computer. Here are the iMac specs and most recent panic report below.
