You're better off using an MCX setting to restrict the app store to an update only mode.

rm -rf /System/Library/LaunchAgents/com.apple.storeagent.plist && rm -rf /System/Library/LaunchAgents/com.apple.store_helper.plist

basic but does the trick

Although in my dotfiles-type setup script I just include:

sudo defaults write /Library/Preferences/com.apple.appstore restrict-store-softwareupdate-only -bool yes

rm -rf /System/Library/LaunchAgents/com.apple.storeagent.plist && rm -rf /System/Library/LaunchAgents/com.apple.store_helper.plist

Exactly what I'm looking for, many thanks!

rm -rf /System/Library/LaunchAgents/com.apple.storeagent.plist && rm -rf /System/Library/LaunchAgents/com.apple.store_helper.plist

doesnt work for me, I'm running 10.10.2 is that why?

Yeah it looks like those are gone in 10.10.X, not sure what the replacement is I'm afraid though.

HI

Is there a way to enable app store but block updates as it is going to be a managed solution. I would like to push all updates via JSS only

Thanks

I know that this is an old post but wanted to let you know that this solution worked for me

Go to the "Applications" tab under the "Restrictions" payload in a Configuration Profile. Check "Restrict which apps are allowed to launch" and then add "/Applications/App Store.app" (without quotes) under "Disallow Folders".

Works like a charm.
