How to Install Safari Beta and Finally Get the Icons
Apple made Safari Technology Preview Release 58 available this week for people using macOS High Sierra and developers using the macOS Mojave beta. If you are already using a previous version of Safari Technology Preview, you can update your version from the Updates tab in the Mac App Store. If not, you can download it right here .
The newest version of Safari adds two new features. In particular, it (finally) introduces badges and offers automatic strong passwords, so you can force the browser to create a password for you when you need to update your password or you create a new account.
There are also some new WebKit features that you can read about here .
As for the icons, they still won’t show up from the start with the new version. You will need to enable them separately by going into the Safari preferences menu, selecting tabs, and then checking the box to have the browser display website icons.
