Determining the version of Adobe Flash on an OS X system

You can determine the version of the Adobe Flash Player present on an Apple OS X online by visiting the the Adobe Flash Information page at BrowserSPY with a web browser. You will see information similar to the following displayed, if the Adobe Flash Player plug-in is installed for the browser.
Flash version via JavaScript 21,0,0
Flash version via navigator.plugins object Shockwave Flash 21.0 r0

Note: you may see commas, instead of periods, between the parts of the version number. Also, this shows you the version for the Adobe Flash Player plug-in installed for that browser. The plug-in version for other browsers on the system may differ. E.g., the version you would see if you visited the page with Google Chrome may not be the version you would see in Firefox, or what you might see for Safari.

Or you can obtain the information from a graphical user interface (GUI) on the system by the following steps:

  1. Click on the Apple icon in the upper, left-hand corner of the screen then select About This Mac
  2. Click on More Info; this step is needed on earlier versions of OS X, such as Mountain Lion (version 10.8), but not later versions such as Yosemite (version 10.10)
  3. Click on System Report then select Software and then Applications.
  4. Scroll through the software list until you see "Adobe Flash Player Install Manager". You will see infomation similar to that shown below:

    Adobe Flash Player Install
Manager info

You can obtain information on the version of the Adobe Flash Player present on the system from the command line, i.e., from a Terminal window, by running the system_profiler command and then piping the output from that command into the grep command. If you look at the 8 lines after it appears, you can also see when it was last updated and the location for the application on the system.

$ system_profiler SPApplicationsDataType | grep "Adobe Flash" -A 8

The Adobe Flash Player application can usually be found at /Applications/Utilities/Adobe Flash Player Install An alternative means of determining the version from the command line, i.e. a shell prompt, is to look for the line that occurs after CFBundleShortVersionString in the Info.plist file for the software, which is found at /Applications/Utilities/Adobe Flash Player Install

$ grep -A 1 CFBundleShortVersionString "/Applications/Utilities/Adobe Flash Player Install"

Or, to see just the version number for CFBundleShortVersionString , you can use the following command:

$ grep -A 1 CFBundleShortVersionString "/Applications/Utilities/Adobe Flash Player Install" | cut -d">" -f2 | cut -d"<" -f1 | tail -n 1


You can see the version of the Adobe Flash Player plug-in installed within Firefox by clicking on the three horizontal bars at the upper, right-hand corner of the window, which will open a menu of options, then select Add-ons. Under Plugins, you should see a Shockwave Flash entry that will tell you the version of the plug-in installed within Firefox.

Firefox Shockwave Flash Plugin

If it is out-of-date, you can click on Update Now to update it.

Google Chrome

You can determine the version of the Adobe Flash plugin installed within Chrome by typing chrome://plugins/ in the address bar within the browser. You will then see information on all of the plug-ins installed within Google Chrome, including the one for Adobe Flash Player. Note: the version number of the plug-in installed may be different than the version installed for other browsers on the system or shown by the operating system when you use the GUI or command line methods. E.g., you could have an older version installed as a plug-in.

  1. Hit the Command and comma keys simultaneously to open Sarari's Preferences windowa
  2. Click on the Security icon.
