Etrecheck reports that the System Integrity Protection is disabled. How can it be enabled again?
Reboot the computer to Recovery mode:
Hold cmd+r while restarting
Select Terminal and enter:
csrutil enable
Boot the computer again normally.
You can also select the recovery drive by holding down the option key while booting the computer. If you cannot select it then I am wondering if there's some other problem happening that is confusing Etrecheck.
You tried to install Big Sur but it couldn't? I have zero experience with Big Sur and don't really know what changes it has wrought upon the drive structure landscape. If you did have a failed installation it sounds to me like it really messed up your drive and you will have to perhaps boot to Internet Recovery and start completely afresh. :-(
Thanks for the reply but I am unable to boot into the recovery mode.
I get error 5101D and it stops at the beginning
Well yes! I cannot boot into recovery mode.
Then I get error 5101D
When I do a web search the only two hits it seems to find refer to this being something in Big Sur. Is Big Sur involved in any manner on your computer?
Tried to install but couldn’t
I cannot boot into recovery mode bc I get error 5101D
