on my MacBook, I booted to RECOVERY TERMINAL.
I get this error “sudo command not found”
critical commands like sudo, brew, su and others are missing from /bin /usr/bin /usr/sbin
i searched with ls -la /usr/bin | grep sudo
Can a bad actor with physical access to my machine delete these from machine? (No Firmware Password Set)
how do I install them back?
When I boot my MacBook with my regular username, sudo and everything else works.
How do I make sure the system recovery software, boot loader and its components are updated.
P.S: I have upgraded to MacOS BigSur
