Dissenter Browser

1. Install the app as normal. (Drag and drop the icon into applications)
2. Go to the Launchpad and launch it. It will be denied as it is from an unknown source.
3. Open System -> Security & Privacy. If the setting isn't "App Store and identified developers" turn that on.
4. There will be a message about Dissenter. Click on "Open it anyway"

You should only need to do this once. It should work fine after that.

For Big Sur:

1. In the Finder on your Mac, locate the app you want to open.
2. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
3. Control-click the app icon, then choose Open from the shortcut menu.
4. Click Open.

This solution doesn't work for Big Sur as the security boxes don't open with a message only highlight the circle.
