When I run
sysctl kern.securelevel on my Mac, it gives me a value of 0.
I'd like to increase the kernel security level on my computer. I want it to give me a 1.
Can I do that?
Found the answer in a related question.
Change it temporarily until next reboot
sudo sysctl kern.securelevel=1
Change it for future startup
sudo vi /etc/sysctl.conf
Once in vi editor, press i to enter insert mode, then type
kern.securelevel=1. Next press enter, then :, then type
wq and press enter one last time.
