yeah, its not working for me. Im typing it in terminal it says it doesn't exist.
 
Then go there in the finder and drag core services to the terminal, it will "paste" the directory right in. I bet you are in your home directory.
 
I disabled SIP, and Enabled without fs

Then mounted system drive, but Im not able to change system version plist briefly. I keep getting denied. What do I do?
