dscl create user doesn't work on el capitan

Question

I am trying to create user on OS X El Capitan with admin priviliges from super-user mode. After running /sbin/fsck -fy and /sbin/mount -uw / and launchctl load /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist everything works. But after dscl . -create/Users/USERNAME i got error no such file or directory. I tried it even with SIP disabled but it doesn't work too. Thanks for the help.

Answer 1

Thanks for the reply, but SIP had no effect.

I finally solved it. The problem was /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist that was used in 10.6 and earlier, I was using /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist The dscl commands were executed despite the error with plist and user got created.

Answer 2

In El Capitan, the mounts have been changed so that not even root can edit files in some mounts...ACL changes.

The feature is called SIP and is explained in other stack exchange posts:

essentially, can boot into recovery mode, type csrutil disable, boot back into default user mode, make changes, then presumably, you might want to re-enable csrutil similarly.
