Safari 12 Released for MacOS Sierra & High Sierra
Apple has released Safari 12 for Mac users running macOS High Sierra and macOS Sierra.
The same Safari 12 web browser ships bundled with macOS Mojave by default, so macOS Mojave users will not find the same software update available to any computer running Mojave.
Safari 12 brings a variety of new features and changes to the Safari web browser, including support for website icons in tabs, password suggestions and an alert if you’re reusing saved passwords in Safari, support for toggling pop-up behavior on websites, ad retargeting suppression, improved security features, and Safari now defaults to disabling any extensions that could negatively impact web browsing performance.
If you’re on macOS Sierra (10.12.6) or macOS High Sierra (10.13.6) then you will find Safari 12.0 available to download now from the Mac App Store Updates tab, accessible from the Apple menu.
If you use Safari as your default web browser, or even as a backup or alternative web browser on your Mac, you should likely update to the latest version available to you.
The next major version of Mac system software, MacOS Mojave (10.14), is set to be released to the general public on September 24, and MacOS Mojave includes Safari 12.0 as part of the broader system software update. Thus if you plan on immediately updating to macOS Mojave, you may find it less urgent to update the Safari web browser in Sierra or High Sierra since you’ll be updating system software soon anyway. For the rest of Mac users or anyone who plans on delaying the Mojave update, updating to Safari 12 is recommended.
Many other software updates are available in the Apple ecosystem as well, including iOS 12, WatchOS 5, tvOS 12, and many updates to various apps like Pages, Numbers, Keynote, as well as tons of third party apps. Over the next few weeks, it’s a good idea to periodically check for any software updates for both these new system software versions and for updates to the apps you use and rely on.
