I addressed this problem by logging in safe mode by pressing Left Shift Key during restart and then signing in to my apple account again and then installing the latest OS mac OS Big Sur version 11.1 which has enabled my touch bar again and also is not giving me any problems after reinstall. I believe some of the apple OS updates are not synched with the touchbar firmwere thats why this problem occurs.Īnd the supported firmwere patch is not reachable or is not available for the update.

However after a little bit of research I could conclude that the problem lies in the firmwere update for touchbar which is not in sync with the latest catalina update so when the laptop restarts it cannot find the firmwere for touchbar. after a lot of research I was disheartened by reading many blogs where the logic board replacement solution was provided by apple and for many they had replaced their laptops which were covered under warranty. The Untouchables - Apples New OS Activation for Touch Bar MacBook Pros See the author's 6th attempt (Workflow 6): Also, this site gave me a lot of insight into what I potentially did to create the issue. Especially since mine was fine until I nuked all the partitions. This totally smells like a software issue to me and not a hardware issue. 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.Įverything I read online says you should not wipe all the partitions on the MBPs with the touchbar, only the main OS partition. It worked perfectly fine until I did this and then re-installed the OS. 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). 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. This is after 3 days of banging my head on the desk trying to figure out a way around it. 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. Again, your system will reboot as Apple has updated the system firmware a few times depending which macOS you are installing. Now before doing anything else apply all of the needed updates. In a few hours your system should have finished the OS install. 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!! 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. Restart your system then using the Option key to enter into the Startup Manager select the USB-C installer drive.

I also tried factory OS install (shift option command R) but fails after downloading OS. I have also tried the clean install with and empty disk (command + R) but shows same screen. I’ve tried updating with wifi, personal hotspot and with LAN adapter but I get same screen. When I turn on it says a critical update is required but keeps saying that an error occurred when I try to install. This happened to me after few days of using the new macOS Catalina.
