Hello,
I've seen articles regarding disabling usb storage devices and tried to delete specific kext files in the extension folder. [IOSUBMassStorageClass.kext & IOFireWireSerialBusProtocolTransport.KEXT]. These are fully protected and is not possible to delete. I disable SIP in order to allow this but all is blocked and protected. Has something changed recently. I cannot find any information or articles that says otherwise. Thank you
Beginning with macOS 11.x Big Sur the system volume is now also a signed & sealed volume so you cannot modify the system volume.

Thank you very much!
This is what I needed to know
You will need to create some sort of script that detect a USB mass storage device being inserted then immediately ejects it as a work around. Then have this script start at boot.
