How do I stop Flash update messages on a Mac running OS 10.6.0, which will not support the latest release? Messages pop up several times a day and are becoming very annoying. There does not seem to be a way of stopping them.
You replied to an unrelated topic instead of making a new topic with your question, so it just got buried in the comments. I branched this into it's own topic and gave it a relevant title.
Flash Player supports MacOS 10.10 and higher. Flash Player is notifying you that you need to update, but your operating system is no longer supported, so your best option is to simply uninstall. Running an outdated Flash Player is a bad idea from a security perspective (as is running an outdated OS version). The last update available for MacOS 10.6 was 2011, so you're really hitting the end of this machine being viable for browsing the web (at least in any form that's reasonably secure).
Here's a link to the Flash Player uninstaller:
Uninstall Flash Player - Mac:
If the update messages are indeed Flash Player Update Notifiations, go to System Preferences > Flash Player > Updates tab. Change the option to 'Never check for updates (not recommended)'. This will stop Update Notifiations triggered by Flash Player, but will not stop browser/content from prompting you to install.
Why doesn't Flash Player install on OS X 10.6:
A recent change required for macOS 10.15 results in Flash Player not being able to install on older version of Mac. These older versions of Mac have not been supported for quite some time, although installation was not blocked, this requirement for macOS 10.15 results changes that. If possible, please update to a supported version of Mac - https://www.adobe.com/products/flashplayer/tech-specs.html
