    Hello,

    Not too sharp with this "stuff" anymore, so if anyone might
    give me the exact step-by-steps to follow, would be appreciative.

    I downloaded a .dmg file/program from SourceForge.
    The Developer is fine, but I get the following error messages when I click on it
    to actually install the program:

    “Gqrx” can’t be opened because the identity of the developer cannot be confirmed.

    Tried doing it under Safari and also Firefox. Same results.

    Under preferences in the Apple pull-down, I went to the Security & Privacy icon, and have tried most everything there to allow it.

    I also unlocked it using my Password, and then clicked the Allow All button.

    Doesn't work.

    What should i do, please ?

    Thanks, appreciate the help,
    Bob

    Right or control-click on the installer/application and select "open". You'll then be prompted to confirm that you really want to open it.

    Run this command in terminal:
    sudo spctl --master-disable

    ...and you won't be bothered by that any more.

    I wouldn't recommend bypassing that security feature for the average user. Certainly not without explaining what it's doing, at least.

    Depends on the OS. Some reset after 30 days. Not even that long in High Sierra.

    "Depends on the OS. Some reset after 30 days. Not even that long in High Sierra."

    I understand this can get "reset" with a software update, is that correct?
    If that happens, just run the terminal command again.

    Before "Gatekeeper", the Security/Privacy-->General pane offered THREE radio button choices at the bottom:
    - App Store
    - App Store and identified developers
    - Anywhere

    With Gatekeeper (or perhaps just with newer software releases), the "anywhere" option is removed, leaving only the first two choices.

    Running the terminal command in reply 3 above merely restores the "anywhere" option.
    It's one of the first things I reset when setting up the OS after a software install or upgrade.
    The Mac ran fine with the "anywhere option" for years.
    Nothing has changed.
