Hey, Recently In Big Sur I mount the EFI partition and DELETED the embedded OS folder just to check the HORROR back again. I was stuck at “Critical Software Update Needed You cant use this……..bla bla” After deleting EFI partition I knew I had to re-install the OS which will rebuild the EFI but some how after Few tries with downloading the critical update I booted in to “ Option+Command+R” combo and for some reason It booted straight in to My Login Screen. Anyone ELSE can try this?
