My MacBook Pro has a "Global Reset" error on every reboot since a few days. The exact error message in the error report:
Global Reset
GRC0 = 0x00000400
GRC1 = 0x00010001
I recovered macOS and did all updates, but the error is still present. I cannot find anything about the error codes above. What is the problem?
MacBook Pro 13″, macOS 11.4
I believe I have the same problem. Started after I upgraded to Big Sur.
Every time I restart, it hangs during the restart (with a multi-language error message written in grey on black background) and then restarts again. When the computer is finally started I get the exact same "Global Reset" error message as you.
If I turn off the computer, it seems like it doesn't fully shut down, because every time I start it again, it won't respond, so I have to hold down the power button for ten seconds after which it is fully turned off. After that, I can start the computer again.
These problems happen every time.
I have narrowed down the problem a bit - it seems like this happens only when I have two displays attached to my Thunderbolt 3 Dock (which I always have). I can have each Display connected individually without any problems, but as soon as both are connected I get the "Global Reset".
I have tried everything that I can think of without any luck, including
The only options I still haven't tried is to buy a new computer or buy 1-2 new displays, but for obvious reasons I would like to avoid that.
This seems to be a serious bug in Big Sur as everything has worked perfectly well before I upgraded.
My hardware:
Very similar setup with the exact same dock and two monitors (Dell 2713 and 2718). Global reset also occurs with a smaller USB-C hub running to a Dell 2715 monitor at work.

GRC0 = 0x00000400
GRC1 = 0x00010001
That's what I get every time I try to restart the computer. I have two external displays connected.
Is this just Dell monitors or others too? I've just come across this thread having been struggling with it for months. Mine are a U2419HC (USB-C) and a U2415 (attached via a USB-HDMI adapter).
Sadly, I can't get our helpdesk to log a case with Apple, they simply keep telling me to try re-installing Big Sur and reset NVRAM, neither of which fix the issue.
I've just started getting this error too.
macOS 12.1 (21C52)
MBP (13-inch, 2019)
Dual LG 34" HDMI Ultrawide displays connected via USB-C hubs
Anyone found a fix or isolated it yet?
Been having the same issue too. Glad it's not just me ... but probably won't be getting another MacBook after this.
For me, it's more than this - there's actual instability on the computer where the entire system becomes either unstable or unresponsive.
