Update Safari

Before you do anything, make sure that Safari is up-to-date. Safari is part of macOS and included with macOS. This means when you update macOS, Safari will also be updated. This further means that you need to update macOS to install the latest Safari updates. Here is how:

  • if you are using macOS Mojave or later: Open System Preferences and click Software Update. If there is a new macOS version, click Update Now and then follow the on-screen instructions. You can also turn on automatic macOS updates by checking the ”Automatically keep my Mac up to date.” box.
  • If you are using an earlier version (e.g., macOS High Sierra, etc), open the App Store app on your Mac then click the Updates tab. Then follow the on-screen instructions.

  • Delete stored website data and cookies. Open Safari, click Safari > Preferences > Privacy. Then click the Manage Website Data button. Then click Remove All.
  • One or more of your extensions may be causing your problem. Check your extensions by going to Safari > Preferences > Extensions. Turn off all of them by deselecting the checkbox “Enable… extension.” for all of them. Then quit Safari and open again.
