Pesky Google acting up Google installed something called 

GoogleSoftwareUpdateAgent


That will run endlessly in background every hour, consuming resources and battery life.

Here is a snippet from Console-system log.

It is seemingly trying to update Google software on my Mac.
I have changed its check interval from 18000 (5 hr) to 604800 (once per week) with 

defaults write com.google.Keystone.Agent checkInterval 604800 


but it is ignoring that.

Macbook Air 2012 with Sierra.

How do I fix it, or kill it.
Since I'm by no means qualified to fix Google problems, I ended up using brute force.

First I renamed this folder :
/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/

Then I killed the GoogleSoftwareUpdate update Program with

sudo launchctl remove com.google.keystone.system.agent


First result is in: (Victory)

Aug 16 20:51:06 myMBA com.apple.xpc.launchd[1] (com.google.keystone.system.agent[771]): Could not find and/or execute program specified by service: 2: No such file or directory: /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/MacOS/GoogleSoftwareUpdateAgent


We will see tomorrow if it stays put over night and stops trying to update Google Software every hour.
