Any way to tell if overvoltage occurred?
This night, after a thunder strike my Mac Mini 2018 shut down, and my display said "No Signal". I turned it back on a minute later or so and yet I can not detect damage.
I wonder if it was a brief outage or overvoltage. I have a power strip connected to a wall outlet, and all my devices are connected to this strip.
I looked for previous shutdown causes/codes.
Actually, I managed to find the shutdown code which is -3
According to this:

-3 indicates thermal issues.
Just for grins, I pulled the power strip off the wall socket to see what shutdown code would I get, and interestingly I again got shutdown code -3.
Do these indicate that brief outage was a more likely cause than a power surge?
