In the terminal I am typing:
sudo vi /etc/networks/loopback , but I am getting a permission denied inside the vi editor.
The /etc/networks file has this inside:
## # Networks Database ## loopback 127 loopback-net
Are those three items actual files I can go into?
I am running El Capitan Version 10.11.6.
Edit: I rebooted into recovery mode, typed in csrutil disable, and now when I type in sudo vi /etc/network/loopback I get this output:
E575: viminfo: Illegal starting char in line: /private/etc/networks E575: viminfo: Illegal starting char in line: ^I"^I1^I0 Press ENTER or type command to continue
Then when I press enter, it goes into the vi editor but it still says [permission denied] on the bottom.
