Below are several examples of how to disable this bull roar

from taking precious system resources.


EVEN ON OLDER MACS - (I used MDD running 10.5x)

This started happening to me probably around May or June.

My computer was Held down in some unknown process and then

I installed Little Sntich - and BINGO it's KSFETCH the little

hidden installer that is accessed multiple times daily by Google

to (?).

My computer was rendered almost unusable when these updates would occur

and it was HORRIBLE because they happen so frequent.


Does anyone know why LITTLE SNITCH does not have a

simple area where you can have the Name blocked as

KSFETCH ? Instead of the IP ect? I thought it would have this feature

but no  and KSFETCH gets around this with Keystone

by changing the IP last digit every call.
Amazingly simple and effective.

Google is the robot to fear.





THERE ARE AT LEAST  2 library folders.  (depending on how many users on system)One for root user (current user) and one for

administrator (master file set)


You want to target your Master file set first and then do your users LIbray folders.



method 1:

To stop the ksfetch (Google's auto-updater software) from checking every hour run the following in terminal:


defaults write com.google.Keystone.Agent checkInterval 604800


604800 is a week in seconds. Divide by 7 to check daily.


Keystone agent is generating a new temporary executable file on each update check. This is why Little Snitch is asking repeatedly for permission. If Little Snitch were updated to allow regex for name checking then this could be solved. No doubt this would introduce other issues that would need to be considered.



method 2 :



I have deleted files in LaunchAgents and made the Google files inaccessible = permissions 000 and ksfetch keeps running every hour. The "Do No Harm" company is full of it.




method 3 :

MANUAL method


Go to /Library/Google/ and copy it to your desktop. delete GoogleSoftwareUpdate, Lock it and replace it with your old one.



method 4 :

MANUAL method




first go to your home folder, then to the library folder.  Inside the library folder you will find a folder called Google.  Inside the google folder there is a folder named GoogleSoftwareUpdate.  Highlight this folder and click cmd  i.  The window that pops up is what you need.  At the bottom of this window, you will find sharing and permissions. This is where you would change the settings for the folder. 


That is cmd plus the i key. (⌘+i) simultaneously.



The same dialogue box can be accessed by right-clicking on the folder and selecting 'get info'.



Incidentally, if you trash the contents of the folder and then lock the folder (checkbox at the top of the info window) that will also prevent anything being written to it.

    This seems to be a better / easier way.  In finder go to /Users/YourUserName/Library/Google


    Then right click "get info" or CMD I and change the permissions on the "Google Folder" too read only and lock it.


    You can also do this via terminal for advanced users.


    This  works for Hands Off or Little Snitch in fact you can delete "all the  rules" for KsFetch and it hasn't come back for me in a long time.


    This  may interfere with Google software updates so if your Google stuff  breaks just change the permissions back and update. Then change back if  necessary.


    You can also use the wildcards in Hands Off and  Little Snitch they do work as well. If you the recent versions. Google  it to learn how to use the wildcards.

    I tired going into Finder as you suggested and then rebooted. At first I thought it worked, but a few hours later Little Snitch caught KSFETCH again! Then again!


    I haven't made any rules for KsFetch in Little Snitch. I just tell Little Snitch to accept until I quit or else I will be bothered even more if I deny. I did another search in LIttle Snitch and no rules for KsFetch are there.


    This is driving me crazy because I have been trying to stop this for over a month now. I must be missing something here. I feel this is so invasive of Google with it's annoying auto updater so many times per day. It's neverending.


    I must be missing something here. I'm a little unsure of what to type in Terminal as I don't use it that much. Can someone confirm the code please?

    Hi which terminal command?

  • PurpleApe Level 1 Level 1

    Try these pictures this is real easy.





  • PurpleApe Level 1 Level 1

    If you don't know the basic command line syntax you would be better of not going there. You can damage your system if your not carefull. Just use finder and look at the pictures.


    Hope it helps.
