System Error A Critical Error Has Occurred
Erminia Scharnberg
From my experience, I assume you may be on a touchbar Mac that's needing a firmware update for the touchbar OS. Make sure your computer is on a network that isn't restricting access to certain documented Apple hosts. Also, if your network uses a proxy to connect to the internet, that can make the firmware update fail to apply automatically.
i've gotten these a few times, sometimes a wipe and reload works. At least once I had to take to an Apple Store and it had a systemboard replacement (After I tried wipe / reload, loading the latest combo update via target boot, and trying from a mobile hotspot and from home).
I had the same problem. My LuLu proxy app disabled the networking. I booted the mbp in safe mode (holding shift while starting) and uninstalled LuLu. I found the uninstaller of Lulu in the application package. After that I removed lulu from the network profile settings and rebooted the laptop. Now is everything working fine.
I hope somebody from Apple will shed light on this topic and give some explanations on the T1 firmware update and how to recover it or check that it's broken or why Apple (hardware) Diagnostics thinks that's everything fine if my eyes see it is not??
I have been facing this issue in my A1707 for over a year and days of installing one Mac version to another did nothing. I am okay with touchbar gone.But it is causing my mac to restart automatically with "******" msg that my machine restarted because of a problem is driving me nuts. My mac dont hibernate/sleep since then. Is is same for you people?on a side note reading the console log there is a constant error of dfr display not ready possible hardware error is rolling every seconds. Is it same for any one of you?
I'm joining the club, I got this error about a week ago after my late 2016 Macbook Pro (Big Sur) crashed when I opened the lid.I've been able to log once and the touch bar was working fine. After few hours, I reopened my MacBook and it was crashed again. Since then I haven't been able to log in. I did change my screen but it was like 2 years ago and I only had few crashes before that.
Today I tried to remove everything and install only Windows 10. Every startup, I got an error from Boot Camp saying that it encountered an error and need to restart to restore, but I can close and ignore this error. Everything is working fine except that my touch bar is not showing at all (no ESC or F1 / F2... buttons).
Have had similar issues in the past. As I was working, my Macbook Pro (2017-mid with touchbar) heated up, about two weeks ago. Since it didn't feel right, rebooted it. Apparently, my MPB was updating in the background (at least, that's what I suspect, even though I always have auto installing off). During the reboot I got the same error message. Retrying or shutting down and starting up again didn't help.
When I has this issue before, last year, I managed to solve it by attaching an ethernet cable. Unfortunately, that didn't solve it this time. I was able to boot in safe mode, so I could at least back up my important files. Through safe mode I also installed the updates manually. This still led to the same error message. Resetting NVRAM also didn't help. Using Apple Diagnostics to check for hardware issues also didn't help me, since there were not issues found.
I then reinstalled my Big Sur installation from recovery mode (without erasing my disk), but still, the error message came up when booting. Then I erased/formatted/first aided my entire disk and tried to install Big Sur, but still the same issue. I've tried this many times, but one time it miraculously worked, I could start up my MPB in normal mode without any issues! I set my appearance preferences and was all set to continue working. But then I tried a simple reboot, and the issue came back again... But at least I could verify that my touchbar was working fine, since I was able to test it. I then knew for certain that my issue had nothing to do with any hardware issues as suggested by other people with the same error message.
I tried erasing my disk and reinstalling Big Sur multiple times after but with no luck anymore. I then safe booted, downloaded macOS Catalina and created a bootable installer on an external SSD I have. Booted by holding the option key and selected my bootable installer. It installed Catalina but eventually I got the same error message, I pressed retry and it somehow worked! I could boot normally in Catalina. First thing I did was installing all updates and upgrading to Big Sur again. This caused the issue to come back again... I then thought that it might be an issue with Big Sur, so I wanted to install Catalina back with the intention to not upgrade to Big Sur. After installing Catalina again using my bootable USB installer, I got the same error, but this time retry didn't help me. Again, I was stuck.
I retried formatting/erasing/first-aiding my disk and installing Catalina multiple times. Eventually, after a long, long time, after basically giving up, it somehow worked again. Catalina was installed and I could boot normally. But all my trust was gone.
In the end, I suspect that something went wrong during the first update attempt that also somehow affected the base volume. The base volume was the one volume I couldn't erase or format. I did perform first-aid on it, but that didn't resolve anything. But then again, out of my 30-40 re-installation attempts it worked 3 times, after 2 of those it crashed again, the third time I just didn't touch it again and traded it in. It is very sad to see my MBP go because of a software issue. Other people have suggested to replace the motherboard or touchbar, but I had found that both worked fine. Apple machines aren't cheap, and most people buy it with the intention to use it for more than 4 years as a stable machine to be productive on. Hopefully Apple will help their customers, but the lack of adequate responses from Apple doesn't lead to a glimmer of hope.
Tried all the tricks mentioned about waiting a few minutes before pressing "Try Again" button, using different networks, wifi and ethernet cable but the update always fails.Tried upgrade of OS to Big Sur still have the same message.Tried clean install of Big Sur and still have the same message.
Took machine to local Apple authorised service provider who repeated all of the above, after a while a second set of diagnostics stated it needed a new upper case as the Touch Bar did fail a diagnostic test. Cost circ 600.
I got stuck in this mode recently, coupled with the comments here I was able to get a solution.The Solution: I entered into safe mode (power button and hold shift under the apple logo comes up) and updated my Mac fully, restarted it. Although it got me back to the wifi page after it restarted when I connected to the wifi and updated, it was fixed.
As soon as I finished force delete, Norton dialogue box somehow popped up and asked me to restart in order to complete the uninstall. This appeared strange because I already deleted the software in previous step. (Obviously, there were remnants of Norton still lingering around my MBP. Hint: uninstalling Norton is very difficult...)
After the restart, I started getting the same "Critical software update required" loop error message, and that's how I ended up on this discussion portal. I've tried most of the troubleshooting tactics offered here (3min waiting game, wired ethernet connection, I also considered upgrading to Monterey but didn't), but nothing worked in my case.
My MBP is now fully functional, and the first step that I am planning on doing is take a backup of all my work (music tracks, video edits) to my external hard disk before something else bad happens...
In my case, the issue seems to have been caused by forced Norton uninstall and simple reinstall brought my MBP back to life. So, if this issue happens to you, consider what you have done to your MBP just prior to this error message. You may be able to unwind it...
Having the issue with MBR with Touch Bar with Monterrey. One other user suggest unplugging all peripherals and rebooting. This did the trick. Once device was fully booted up normally, I was able to connect 2 monitors, keyboard, mouse and external USB speaker. All worked as expected.
Same exact issues with multiple units, multiple locations. New purchases and the replacements sent by HP. Honestly not even sure where to go from here. This model is having some issues. Hoping for a solution. Screen says "Printer error occurred F0.01.01.04 A critical system error has occurred....."
We have to power cycle to start printing again. Later in the day the error comes back up after a few jobs go through. We've tried the HP support steps of power cycle, unplug and discharge, firmware reset, firmware update, more resets, replacement printers which have the same issue. Other printers of the same model at different office locations with the same issue despite different programs doing the printing (formats / document types.) The only common denominator is this printer model and error.

Unfortunately you have described the exact same issues we have recently encountered with our printer. It has been out of the box for a month, working flawlessly, until last night some users started getting Windows printer notifications which said "The printer is in an error state" when they attempted to print standard PDF documents. The printer would "spin up" but ultimately not print. It was not displaying an error message on the control panel, but after a restart it has shown an error message which said it was fatal error and required the printer to restart.
The printer in question is a HP Color LaserJet Pro MFP 4301fdn. Firmware: 6.12.1.12-202306030312.
We are printing from Windows 10 Pro, trying PDFs on an up-to-date Adobe Acrobat. We are connected via ethernet in a locally hosted AD domain setting but I am not requiring authentication to use the printer.
In the event log we are seeing these multiple times per minute:
