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



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

Terminal gives me: Could not write to domain...


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

On Launchd: http://www.launchd.info/

The Life Cycle of a Daemon. Terminating processes:
https://developer.apple.com/library...ptual/BPSystemStartup/Chapters/Lifecycle.html


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

< ?xml version="1.0" encoding="UTF-8"?>

If System Integrity Protection (SIP) is enabled, as it is by default, you can't modify any files in /System/Library.

To check the status of SIP, type this in a Terminal window:
Code:
csrutil status

If it's enabled, you'll need to disable it. You should carefully consider whether to take this path.

If it's disabled, then post again, because the plist files should be writable.

Thank you very much! SIP was the problem! Disabled it and was able to run commands correctly.

I enabled SIP again afterwards.

A bit different question (probably wrong thread to ask as well...but still...somehow connected to shutdown as well). I upgraded my Macbook Pro (2013) to Sierra 2 days ago, and this morning I noticed that fans stay on for some 5-10 seconds after shutdown (screen off/lights off). Is this a normal behaviour? It didn'happen in 10.10.

Glad it worked.

And good idea re-enabling SIP.

I don't know. You should ask on a forum like Mac Basics.
