Apple has released Safari 12 update for macOS High Sierra and macOS Sierra. The same browser version is installed by default in macOS Mojave. This is why macOS Mojave users will not find an available update available.
Safari 12 contains many new features and changes, including support for tabbed site icons, password recommendations, site pop-up control, targeted ad protection, improved security, and more. In addition, Safari now automatically disables extensions that can negatively impact browser performance.
If you have macOS Sierra (10.12.6) or macOS High Sierra (10.13.6), the Safari 12.0 update will be available in the Mac Updates tab App Store. If you are using the browser as your main browser, then we strongly recommend installing the update.
The new version of macOS Mojave (10.14), which will be released on September 24, contains Safari 12.0 by default. If you plan to install macOS Mojave immediately after the release, you can skip updating your browser. Otherwise, the new version is worth installing.
Recently Apple has released many updates for other systems, including iOS 12, watchOS 5 and tvOS 12. Updates for several standard applications have also been released. In the next couple of weeks, we advise you to regularly check systems and applications for updates, because there are a lot of them expected.
