Nothing kills productivity quite like a Mac that sounds like a jet engine, followed by a sudden black screen displaying the terrifying message: 'Your computer restarted because of a problem.' This is a Kernel Panic.
Kernel panics combined with overheating usually point to a failure in the relationship between your Mac's hardware sensors and the operating system. It could be a rogue third-party driver (kext) causing CPU runaway, a failing thermal sensor, dried-out thermal paste, or a corrupted System Management Controller (SMC).
This master-class interactive diagnostic tree will help you identify whether your issue is hardware or software, teach you how to read macOS panic logs, and walk you through the precise steps to stabilize your system.
