Even though csrutil disable, vpnagentd process not running

Looks like the big issue is that Mac checks the binary to ensure that it's signed correctly as well: Binary is improperly signed I don't know enough about Mac binary structures to either remove the check for the sign, or update the signature to match after the modification. :(

@xswqaz @garrettskj i was able to apply the patch first part of the patch (nooping the StartInterface), the last part didn't work since no reference to "VerifyFileSignatureCollective::IsValid" was found. The vpnagentd process was able to run after a sudo codesign -f -s - vpnagentd, but it was restarting... maybe something is different with my version 4.10.03104
