Stuck at “critical software update is required” screen during startup
My MBP doesn’t boot up.
This happened to me after few days of using the new macOS Catalina. When I turn on it says a critical update is required but keeps saying that an error occurred when I try to install.
I’ve tried updating with wifi, personal hotspot and with LAN adapter but I get same screen. I have also tried the clean install with and empty disk (command + R) but shows same screen. I also tried factory OS install (shift option command R) but fails after downloading OS. The NVRAM and SMC reset does not help.
However, I am able to use my mac from safe boot mode but touchbar, keyboard backlight and sound does not work from safe mode. I can also use my mac booting from portable usb windows drive but again touchbar, keyboard backlight and sound does not work (everything used to work from the same usb drive before the critical software thing happed).
The internet says it has to do something with touchbar unit, but I didn’t have any issues before. Do you think replacing the touchbar unit will solve the problem?
Esta é uma boa pergunta?

I just started having the exact same issue after upgrading to Catalina. If I unplug all external USBC peripherals it boots up no issue. I can then plug in peripherals once booted up. If I let it go to sleep with these plugged in, it crashes and gets the error message as poster above described. To be continued.

Any updates on this?

Nope, I'm still having the exact same problem. I ended up buying a new MBP.
Replacing the touch bar controller didn't help, I have tested the board with everything disconnected ( disconnected display, touch bar, power button, trackpad etc.) only battery connected, and an external display. It still boots to the same screen, my guess is that the problem is with the motherboard itself.

@dzavoo - Did you get the system looked at? Did you bring it into the Apple Store to see what they said? There has been some chatter on Catalina upgrades bricking systems.

@danj I live in Armenia where we don't have official apple store, but we have apple autosized repair center. The repair center basically did the same thing as I did (installing different versions of macOS including Mojave and sierra) and they told me that the problem is with the touch bar unit and the solution might be replacing the top case (entire top case with battery and keyboard etc..) for $800-$900. Of course I didn't agree to do that because I think the problem is with the motherboard.
