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?

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.

At this point you need to wipe the drive and re-install your OS from an external OS installer drive.

First backup anything important off your drive (TimeMachine)

Next create a bootable OS installer using another Mac system, I personally would stick with Mojave for now as Catalina is still a bit buggy! In any case here’s how to create both:

Restart your system then using the Option key to enter into the Startup Manager select the USB-C installer drive. Once started go to the menu and select Disk Utility and then delete all of the partitions, then reformat the drive as one GUID APFS partition.

Reference: Mac startup key combinations

Now exit Disk Utility and start the OS installer letting it do its thing! Your system will reboot a few times and the screen will also go dark so don’t panic!!

In a few hours your system should have finished the OS install. Now before doing anything else apply all of the needed updates. Again, your system will reboot as Apple has updated the system firmware a few times depending which macOS you are installing.

Did that work?

Thank you very much! I’m going to try that and I’ll let you know about my progress

UPDATE: I tried installing both Mojave and Catalina, when I try to install Mojave it shows an error however Catalina is installing successfully but shows exact same error during startup. I believe I have hardware issue :(

@dzavoo - What was the error message you got with Mojave during the format or install?

Time to visit an Apple Store! Please let us know what they tell you.

@dan I have a question.

So I tried every possible software fix (nvram/SMC reset, re-installing different version of macOS from usb device and from internet recovery, also tried to boot from bootable macOS ssd etc.) and everything shows the exact same screen.

I also tried to remove everything from motherboard (disconnected display, touch bar, power button, trackpad etc.) only battery connected, and an external display. and still got the same screen. Does this mean that the problem is 100% with the motherboard?

I also tried to replace the touch bar controller cable (not the entire touch bar unit just the connector cable) do you think I should replace the full touch bar before buying a new motherboard? or it is 100% with the motherboard.

完成的

Yes, you have a logic board failure.

Unlike older models which you can replace the SSD and even older models you could replace the RAM this series has both soldered!

I sh*t you not....a couple hours after posting this, my 2017 MacBook Pro 15 (A1707) booted up just fine, and the touchbar was working again. This is after 3 days of banging my head on the desk trying to figure out a way around it. I'm thinking the macOS 10.15.3 update had something to do with it, since it just came out and my system updated to it while in Safe Mode.

I do know for a fact what killed it was me wiping the entire drive (all partitions, including the one specifically set aside for the touchbar). It worked perfectly fine until I did this and then re-installed the OS. Why did I do this you ask? I just bought this MBP from someone on Facebook and I wanted to be sure I was starting from a completely clean slate.

Everything I read online says you should not wipe all the partitions on the MBPs with the touchbar, only the main OS partition. This totally smells like a software issue to me and not a hardware issue. Especially since mine was fine until I nuked all the partitions. Also, this site gave me a lot of insight into what I potentially did to create the issue. See the author's 6th attempt (Workflow 6):

Hey guys,

I had exactly the same problem. This is what I did. I rarely shut down my computer, this time I thought I'll give it a rest. I had Samsung SSD and a WD MyBook Duo both plugged into the USB C ports. Although I have booted with the SSD before no worries, this was the first time with the MyBook Duo. I had the message come up on the boot up screen, I pressed shut down. Booted up again in Safe Boot (hold left shift until Apple logo had loaded half way, release) Got an access to the homescreen. Disabled Wifi and unplugged the MyBook Duo from USB C. Pressed restart and it booted up no worries. I think the culprit here might have been the external hdd. I'm not saying that this is the fix for everyone but if you're having a similar issue and have something plugged into USB C that you've never have before on a boot up, might be helpful to go through the process I did.

Hope somebody finds this useful

I changed the screen for a MBP 2017 with touchbar and afterward it get this problem, clean install and get this message at the end, solved by remove the screen cable from motherboard, since the t1 chip recognized the not original screen, then on the hdmi external, I got to the setup thing to finish my installation. Once done I plug back the cable lcd and now the Mac work normally, also I installed Sierra. Not latest osx

After exhausted all recovery method, I went to App Genius. Straight away they ask me to change logic board. I refused and I saw your post.

Tried bootable Mojave method.

Immediately after reinstallation able to boot into MacOS. Touch bar working.

Installed all system updates (besides Catalina), and it auto restart while installing system updates, whamp! Hit with critical software update.

So it's a loop again.

(I did replace my screen with a third party repairman due to the 2016 MBP touch bar encountered backlight failed issue). Not sure if this is related.

-Additional update. After 'Try Again' and showing Apple logo, the Touch Bar flashed/blinks around 3 times. Each time less than a second.

-Tried disabled my router firewall, no vail.

Update (05/06/2020)

After reading the TS that he disconnected the display cable, I figured I do the same since my display is not original anymore.

Before dismantling, I figured I performed a SMC reset and connected my Mac to my TV. And somehow it works! I restarted once, and shut down once before power on. No connection to tv is needed now. Touch bar working. Weird.

(Apparently I wrote too soon. 5 mins in mscOS Mojave, the middle of the screen came out something weird and it goes into the boot loop again). Nothing works now.

I found a way for fixing it by my self.

The Touchbar Controlboard is attached to a flex cable under the Logicboard and for some reason the Touchbar Controller broke due to a clean install maybe? So i bought a new one from AliExpress for 8€ and changed it the replacement was super easy. Only the logicboard has to be removed you dont need a new Touchbar for this. After that all it needs is a reboot with a wired internet connection.

Hello, you mean replacing the flex cable needs the whole logic board to be removed? I need to remove the fingerprint ID sensor and fan too I believe? (judging by the guide).

完成的

No you don’t have to remove it just unplug it from the logicboard. Both are screwed to the topcase

完成的

Understood. Thanks. I shall purchase one to try it out. I'm now permanently boot into bootcamp. Else it's just a large brick ...

You can boot into safe mode turn WiFi off and then reboot normally. This allows you to get access to your normal user account with all functionality except the Touchbar.

Important is to turn your WiFi off when you shut it down or putting it in standby

Christopher: Thanks very much for the knowledge that you have brought to this conversation. Your experience made me wonder if my own issue might be a poorly seated plug. Sure enough, after more than a week of frustration, I carefully re-seated the Touchbar flex cable, and part-way through bootup, the Touchbar lit up and after another minute or so, the boot process completed and I had a completely working Macbook again. So relieved!

This still leaves me with one other A1706 which has failing Touch ID ...

UPDATE: Just fixed the other A1706 as well! It's amazing how little info there is about these two problems (Touch Bar and Touch ID malfunction). What exists points to some kind of hidden T1 firmware that is inaccessible to us. And maybe that's kind of true, but both issues were ultimately resolvable by an end-user here. In my case, the Touch Bar problem was as simple as the flex cable needing re-seating, and the other Mac's Touch ID/fingerprint issue resolved by going back to High Sierra (and probably an SMC reset prior).

Hi Everyone,

The integrated SSD in my macbook pro 15" A1707 was broken and can't be used anymore, so I did install Catalina into external SSD and stuck with this kind of problem ( A critical software update is required for your Mac….).

Is it even possible to install these firmware updates on an external drive? …If no, a device with a broken internal SSD would no longer be usable/ trash.

Your hardware should be OK! The issue is a software update glitch. You'll need to find your way to an Apple Store as they have then needed tools to fix this!

My 2017 MacBook Pro 15” is literally destroyed after updating to Catalina. The Touch Bar issue made the computer get stuck in the critical software update loop. After bringing my laptop to a local repairman, they tried everything and suggested replacing the logic board. 1.5 years ago this computer was worth $3k now it’s complete trash. Can Apple be held responsible? Anything else I can do to fix it?

Uhm I have  a 2016 MBP and have been getting that “error” message on and off for YEARS. I even got it when the laptop was like 3 days old. Had the laptop replaced by Apple entirely once still getting same critical update screen. Think why would Apple have a critical update that is not listed on the official support Apple com website where ALL downloads are available particularly for OS. As of right now there are no updates for Catalina other than .2 .3 .4 .5 and the combo updates. Previous OSs all have some security updates available. But why would this update not be listed there. I’m still getting it after fresh install and install of the newest available 10.15.5. It makes no sense that Apple would have a critical security update immediately following a OS update. It’s because it’s not Apple—it’s a sign of malware in the efi aka firmware. This type of malware is both well documented and real and has been around since at least 2016

You say this with such certainty, and yet it's clear that you have little understanding of this problem. The "critical security update" is actually the TouchBar firmware install, because the TouchBar is actually a separate piece of ARM-based hardware with its own OS ("EmbeddedOS"). Anything that interrupts the download process, the installation process or the logic path between the host machine and the TouchBar will generate this error

完成的

Time to visit an Apple Store as they have the magic to fix the OS due to the glitch in the OS updater.

They magic is changing logicboard for 1000$
