I didn't see you didn't mention anything about installing the Post Install Root Patch.
From my experience, my machine, MBP (mid2010), becomes pretty unusable after any OS update until I run those. Trying to boot, install assistant etc etc is slow / non-responsive at times. Unplugging my second monitor helps and honestly is won't get recognized until I run those patches.
Glad you got your machine working, and you know what to do if you want to mess around with trying to update again 🙂
You're right, ChrisOSX... I forgot to point out that - obviously - the Post Install Patch has always been installed.
While you provoke me ;-) I'll describe what I tried to do, to no avail
🙂
First I emptied all the "Launch Agents" and "Launch Daemons" folders in the Root Library and Home Library
I also checked that in System Preferences, Users and Groups, Login Items there were no applications and the same thing in the various StartupItems folders.
I have deleted the extensions in the root /Library
I also tried booting in safe mode, noting that in safe mode the menu bar appeared and the keyboard worked perfectly.
I deleted all MyHome/Library/Preferences and also those in the root /Library.
In all of this, I also tried multiple times to reset SMC, reset PRAM, reset EFI boot recreated with OCLP 0.4.3, but without success.
I also tried to play with the System Preferences but, to act, I was forced to reboot every time in safe mode or it was impossible to change something; clicking nothing happened, ditto trying to move with the cursor arrows on the keyboard.
I finally created a new user with admin rights and verified that everything worked fine here.
After that, in order not to have to waste time recreating Account, Mail, etc., I preferred to restore from Time Machine and so I was also able to experience the new excellent way of working Time Machine in doing restores.
I repeat that the problem started appearing immediately after inserting the EFI Boot obtained with OCLP 0.4.4N and restarting the Mac. Restarted, not reinstalled.
You will have realized that I am able to go through the System piece by piece. In 30 years I have never encountered a problem that I was not able to understand and solve directly..., as it has happened now.
Finally, I give the benefit of the doubt that the problem was caused by Boom3D which I never reinstalled. Mah! However, I had removed Preferences and Extensions, etc. everywhere... Boh!...
Ah! Another question is about Adobe Creative Cloud Desktop which was updated on the morning of day 9 and I am now preventing the update from. But, I said, I had deleted all startup items, including this app ...
Who knows what may have caused OCLP 0.4.4N... (???)
The fact is that @Khonokernel has closed the problem page in GitHub and so I can only write here, as I doesn't speak English and so I not have a feeling with Discord
