Manually set timer forcing application exit on shutdown

[Susurs]

Hi!

Could somebody, please advise me on how to correctly manually set timers to force processes to quit when mac is shutting down in macOS Sierra?

Commands below were working in Yosemite but does not work in Sierra (10.12.1):

sudo defaults write /System/Library/LaunchAgents/com.apple.coreservices.appleid.authentication ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.coreservices.appleevents ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.diskarbitrationd ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.mDNSResponder ExitTimeOut -int 1

sudo defaults write /System/Library/LaunchDaemons/com.apple.securityd ExitTimeOut -int 1

This is what I get in the terminal: Could not write domain...

Not a programmer, so I am sorry if I say something totally wrong

Maybe some info on the following pages could help to answer my question:

P.S. Here is my com.apple.coreservices.appleid.authentication .plist in /system/Library/LaunchAgents...

SIP was the problem! Disabled it and was able to run commands correctly.
