Security Breach
My mac terminal doesn't have sudo, chmod & other command , also unable to find sudo file in any of the possible location. I didn't touch or delete any system files recently. it may be possible that i installed some apps from outside AppStore, but i don't think i give full sudo permission to them.
Should I reinstall macOS. I'm using mac mid 2012 13" its running on catalina 10.15.7 & i do recently get a security update.
Please share your thoughts.
MacBook Pro 13″, macOS 10.15
