Blocking "try the new safari" and "upgrade to macos sierra" banner notifications?

[jhuls]

Is there a way to block these pesky banner notifications? I just upgraded some systems to El Capitan as we're not prepared to deal with the Sierra headaches and these notifications are popping up all over. It's especially irritating in a lab environment.

You need to run your own apple software update server to do that. Try using Reposado (https://github.com/wdas/reposado) to host your own Apple software updates. And Margarita is a nice web front end for Reposado (https://github.com/jessepeterson/margarita). I use that and I never pushed out the banner notifications when they came through so my users didn't see them.

Thanks. There's a work request in for the guys to setup an apple software update server on a mac mini the dept purchased so I guess once that's up and going this can be dealt with. I was hoping I could just disable the automatic update feature in the app store system preferences for the time being but the banners keep coming up.

@jhuls To dismiss the Try the New Safari notification, I modify the com.apple.Safari preference using the Defaults command.

defaults write com.apple.Safari SuccessfulLaunchTimestamp -string "5.108473e+08"

I do the same for the New to macOS

defaults write com.apple.touristd seed-https://help.apple.com/osx/mac/10.12/whats-new -date "$(date)"

Hmmm.

$ defaults read-type com.apple.Safari SuccessfulLaunchTimestamp
Type is float
