My High Sierra installation did not come with a recovery partition, only internet recovery so I don't have csrutil. It's not in usr/bin, or the base install volume either like many have suggested, Single User Mode does not provide a csrutil either.
I have looked through the stack threads on the issue, and can't find a single solution other than upgrading or reinstalling, neither are an option for me currently. I do not have access to a High Sierra version of cocoadialog (v3.0.0beta7/v2.3.7) so I can't use recover partition installer app either.
Does anyone have any suggestions on how to disable SIP at this point?
