Pesky Google acting up
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.
