Sometimes I see a ksfetch process on my Mac. After a little googling I found out that it is Google software updater. However, there is no detailed answer i.e. what is ksfetch process used for? Is it really required? Can I get rid of it? Sometimes it uses my internet bandwidth so it frustrates me hence the query. Thanks.

  • Why not just block KSFetch with Little Snitch by denying connections? Would that work? – Frank Feb 15 '19 at 22:55

Keystone Fetch / ksfetch

The ksfetch process on OS X is part of Google Chrome's update mechanism. The ks prefix is an abbreviation of Keystone. The process appears to be responsible for fetching updates to Google's products. It is this role that uses your bandwidth.

Using slick's answer you can disable the corresponding process that uses ksfetch.

Alternatively, it appears possible to adjust the frequency of update checks:

Entering the following code into your terminal will make it check once a week rather than every few hours:

defaults write com.google.Keystone.Agent checkInterval 604800

Yes, you can disable it.

To do this just for you in Terminal type:

~/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py --uninstall

for all users:

/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/install.py --uninstall

On some machines it's ksinstall instead of install.py.

  • Thanks. Can you also answer other parts of the question like what is this process used for? Is it required? etc. – Saurabh Hooda Sep 29 '15 at 7:59

    install.py is called ksinstall on my machine. – Lenar Hoyt Jul 12 '16 at 11:56

You can uninstall it, type /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/ksinstall --help to see available options.

--nuke can uninstall everything related to it, just like this: /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/ksinstall --nuke

  • What's the difference between uninstall and nuke? – Lenar Hoyt Jul 12 '16 at 11:56
  • Run that ksinstall --help command, you will find out. <br/> [--nuke] Remove Keystone and all tickets. [--uninstall] Remove Keystone program files but do NOT delete the ticket store. – Yiling Jul 12 '16 at 18:14
  • I had already removed it with the uninstall command so I cannot check without reinstalling everything. Thanks! – Lenar Hoyt Jul 12 '16 at 19:36
  • Should be ~/Library etc. – matt Apr 5 '18 at 10:32

They have changed this command to --nuke instead of --uninstall and the path is now different as well. So the new command for all users would be:

/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Resources/GoogleSoftwareUpdateAgent.app/Contents/Resources/ksinstall --nuke

    Welcome to Ask Different. We like answers to stand on their own. Could you either edit this to explain the essence of the solution or perhaps edit the other answer with this update. Bonus points for identifying what version of the app needs the new command argument. – bmike Mar 14 '16 at 14:15

There is an issue with Google Chrome that it creates a temp file to check for updates every x hours. Since it's making a new temp file for some reason it sets off Little Snitch, which is quite annoying.

By entering the following code into Terminal, it will make it check once a week rather than every few hours:

defaults write com.google.Keystone.Agent checkInterval 604800

Hopefully one of the next versions of Google Chrome they will address this, as it is very annoying having to click allow/deny every x hours.
