[SOLVED] Urgent: How do I stop App store from "Installing" the 10.11.6 upgrade

[powerpcg5]

I must have clicked the Update All button instead of just updating iTunes.
How do I cancel the "Installing" message/procedure in App Store?

I've tried deleting the /SoftwareUpdates folder in /library but everytime I start App Store, it goes to trying to install 10.11.6

Solved! Sharing this in case others have a use for this info.

Go to /Library/Updates and remove the folder containing the OSX 10.11.6 updates
The folder will named with the product key, i.e. /Library/Updates/031-61467/***** bunch of files

Then open up Activity Monitor, and Force Quit the process called "softwareupdated"

When you relaunch "App Store", all will be well again... and you can do your 10.11.6 update at a time of your choosing.
