Error - panic Sometimes, when I open my MacBook Pro I get a notification that it was shut down due to an error. I performed a factory reset hoping that this will clear the issue but a couple of days later the same thing happened. Then when I check the details I get a list of things that I personally don't understand. The first few lines are: panic(cpu 0 caller 0xffffff7f9e5488b4): "[IGPU] sendHostToGucMessage: Firmware communication error: no action response!\n" @IGGuC.cpp:3743 Panicked task 0xffffff869a1e4350: 7 threads: pid 1: launchd Backtrace (CPU 0), panicked thread: 0xffffff90324ad000, Frame : Return Address I own a 2020 MacBook Pro running macOS Monterey. Please keep in mind that my knowledge over OS and hardware is a bit limited

Hi,

Try to run Apple Diagnostics if it reports Thunderbolt related error(NDT001 to NDT006).
