Adobe Flash 11.3 Enable or Disable Silent Update Package

Flash Logo

Adobe Flash Player 11.3 for Mac has a new “Silent Update” feature, detailed here:

“The background updater being delivered for Mac OS X uses the same design as the Flash Player updater on Windows. If the user chooses to accept background updates, then the Mac Launch Daemon will launch the background updater every hour to check for updates until it receives a response from the Adobe server. If the server responds that no update is available, the system will begin checking again 24 hours later. If a background update is available, the background updater can download and install the update without interrupting the end-user’s session with a prompt.”

Supposedly it will allow Flash to update itself with no user interaction but I can’t confirm this until another Flash Update comes out.  Anyway I’ve put together a really basic Package the turns the feature On for anyone who wants to give it a try.

It  simply puts a new mms.cfg files into /Library/Application Support/Macromedia/ with the following 2 lines of text:


This package can be deployed via the normal methods. (ARD, Munki, Casper)

& here’s a PKG todo the opposite – AutoUpdateDisable = 1 & SilentAutoUpdateEnable = 0

  1. I’m guessing that updates will still require an administrator password to install once their downloaded? I like the idea of keeping Flash updated in the background, but in our environment users do not have admin rights and I don’t want Flash prompting them for an admin password.

    • Hi Cody

      Yeah I suspect you’re right. All I can see is a LaunchDaemon to fire this up every 3600 seconds. /Library/Application Support/Adobe Flash Player Install Manager/fpsaud As to what happens when an update is available I don’t know. I suspect it will just run the package and prompt as per running it manually. Although it could be like Google Chrome and just update. Will see if I can findout.

  2. No. I don’t want more google style auto installing on my Mac!
