I'm trying to temporarily disable KEX signing enforcement on my MBP since my company's VPN client (GlobalProtect) is failing the signature check now. This started yesterday when I did the OS upgrade to Sierra yesterday.
The solution should be running this command:
sudo nvram boot-args=kext-dev-mode=1
The problem is that I am getting the following response, and I can't figure out what it means or what to do about it (meaning I can't connect to my company network, too).
nvram: Error setting variable - 'boot-args': (iokit/common) general error
Does anybody have any ideas of things I could try or otherwise look at to track down the problem?
