    System extension blocked! popup warning.
    this is a first. got this just now.

    not sure what this means or do I need to be worried? ran malwarebytes and it found nothing.

    I only have three programs that are allowing incoming connections in my firewall.

    garageband
    firefox
    com.apple.Webkit.Networking.xpc

    what is the com.apple.Webkit.Networking.xpc? can I disable this one in the firewall?

    As long as you can enable it again, I donít see how it will hurt to disable it?

    Oops, I came across this, https://discussions.apple.com/thread/8239067

    Itís part of Safari, and other browsers, so no donít disable it.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    First blush...looks to like someone launched an old app (or was trying to print)...and the app needed to use a old extension relating to an old HP printer app or driver or extension.

    Remember a lot of these pop up warnings are for the safety of the user...and many of them are false positives. Just like when you download an app from the internet & open it for the first time...many times you get the pop-up warning (are you sure you want to open this)...or the pop-up warning Safari gives if you visit some non-https websites. Many of these non-https sites are safe.

    Pretty soon there will be a pop-up window warning for just about everything...and we won't be able to do anything on the internet without being worried about the next click!

    By the way. I'm thinking maybe this was already on the computer (maybe from a backup or clone of an old hard drive)...and not something that came from the internet recently).
