Safari Now Syncs and Manages All Your Web Extensions Across iPhone, iPad, and Mac « iOS & iPhone :: Gadget Hacks

It’s been a year since I had access to a real Safari extension on my iPhone and iPad, but it’s been around for much longer on my Mac. To get the same thing installed on all devices, I always had to find the app in the App Store, install it, and enable the extension on each device. Now Apple has streamlined this process to make it easier to install and manage extensions across devices.

Starting with iOS 16, iPadOS 16, and macOS 13 Ventura, you can share Safari extensions between iPhone, iPad, and Mac by enabling a simple setting on each device. Then, one device can quickly install compatible Safari extensions on other devices. You can then enable, disable, and tweak them from one device and sync the settings with your other devices.

Enable Extension Sync on iPhone or iPad

Turn on the Share Across Devices switch in Safari settings on your iPhone or iPad to sync extensions across all your iOS 16, iPadOS 16, and macOS 13 devices.

  • Settings -> Safari -> Extensions -> Share between devices

Enable Extension Sync on Mac

In Safari Preferences on Mac[デバイス間で共有]Check the box to sync extensions across all iOS 16, iPadOS 16, and macOS 13 devices.

  • Safari –> Preferences –> Extensions –> Share Across Devices

Quickly install shared extensions

If you already have Safari extensions on one device and don’t have them on other devices, the Extensions settings on those other devices will have a new[他のデバイスで]section is displayed. These settings show each app that isn’t installed, but show an iCloud download button to quickly install it.

However, there are pitfalls.[他のデバイス]The only apps that appear under are those that currently have Safari extensions enabled on one of your other synced devices. If it’s installed but disabled on another device, it won’t appear in the list until you activate it there. If you see the extension in the list, turn it off on other devices and it will disappear.

When an app is installed from the “On other devices” section, it will be moved to the “Allow these content blockers” or “Allow these extensions” groups.

Tips: Enable automatic app downloads on all your devices so that when you install an app on one device, it automatically installs on your other devices. In iOS 16 and iPadOS 16,[設定]–>[App Store]–>[アプリのダウンロード]([自動ダウンロード]) to set the features.

Synchronize extension settings

When you sync Safari extensions, any extension you enable on one device will be enabled on your other devices as long as the associated app is installed. Turning off extensions on one device turns them off on all synced devices.

However, permissions for each Safari extension are not always synced across devices. So setting one extension to “Allow” on every website and changing it to “Verify” may not affect the permission on other devices. After installing the extension, website permissions may be the same as on other devices, but further changes may not be synced.


The most important restriction is that each Safari extension must be compatible with each device. Not all iPhone apps are available for iPad and Mac, and some iPad and Mac apps only support these platforms. Some of his Safari extensions on your Mac aren’t available from the App Store, so they won’t show up on other devices.

Depending on the Safari extensions you use, the number of extensions that sync with other devices can be severely limited. For example, I had 7 Safari extensions on my iPhone, only 1 of which was shared with my Mac.
