Ahead of macOS Mojave, Apple releases Safari 12.0 for macOS High Sierra & macOS Sierra

Apple released an update to the Safari desktop app for Mac. While macOS Mojave comes pre-installed with Safari 12, you can update to the latest Safari update for users running macOS Sierra 10.12 (released 2016) and macOS High Sierra (released 2017), and is good for users who run these older macOS versions on an unsupported Mac.

 

The Safari 12 update is recommended for all macOS High Sierra users and contains improvements to privacy, compatibility, and security. This update:

  • Adds the ability to view website icons in tabs
  • Automatically suggests and fills a strong, unique password when creating an account or changing a password
  • Flags reused passwords in Safari Preferences
  • Adds support for allowing or blocking pop-ups on specific websites
  • Prevents embedded content and social media buttons from tracking cross-site browsing without permission.
  • Suppresses ad retargeting by reducing advertisers’ ability to identify Mac devices uniquely
  • Automatically turns off Safari extensions that negatively impact browsing performance
  • Improves security by only supporting legacy Safari Extensions that have been reviewed by Apple
  • Improves security by discontinuing support for most NPAPI plug-ins

This update also includes updates security, outlined in an Apple support document on the security content of Safari 12.
