Install as unsigned extension
Extensions installed as unsigned aren't updated automatically. To update the extension you should download it and install as unsigned again.
Unsigned extensions are installed as separate instances. If you have Web Scrobbler installed from the App Store, you should disable it; otherwise you'll get double scrobbles.
Follow [these instructions][get-builds] to get extension builds.
Here is a short guide how to install an unsigned extension on Safari.
- Open Safari settings, hit "Advanced", and turn on "Show Develop menu in menu bar".
-
Open the folder of the Safari extension in terminal, and run
chmod +x "Web Scrobbler.app/Contents/MacOS/Web Scrobbler". You may need to use sudo. -
Secondary click/right click the Web Scrobbler application, and hit open. It will give you a warning that you can ignore, and then launch the application. You cannot double click to open, as the warning given by MacOS will not be ignoreable.
-
You should now be able to enable the extension in the Safari extensions settings.
