Anyone know how to speak Kernel Panic?

Swapped out the drive on a ~2014 iMac for an SSD several months ago. Not sure if that could be causing the issue but there have recently been kernel panics occurring from time to time. Anyone know how to read these?

no 3rd party kernel extensions.

which also implies no anti-virus with a kernel extension poking around where it shouldn'

The SSD (or as simple as the sata cable) is one suspect.

Also there is 3rd party RAM, so that is the other suspect

Probably, you should follow this thread at Reddit:

ELI5: How does a kernel actually speak to the hardware? from explainlikeimfive

@jigneshpadhiyar

I'm not sure if I get why you posted this?

@jigneshpadhiyar

I agree. It is off-topic
