Disable Rootless on Headless Mac I understand that the way to disable rootless is through the Recovery Partition. However, I have a remote, headless Mac with an attached bootable clone drive that I access via Screen Sharing. Can I either:

a) Boot into the recovery partition using the command line?

or 

b) Boot into the clone and change the rootless status of the HD from there?
If csrutil disable doesn't work, you can try to disable it via boot args, e.g.

sudo nvram boot-args="rootless=0"


then reboot
