Extensions preferences

Use Extensions preferences to enable and disable Apple and third-party Mac extensions. Mac extensions, such as Markup, add extra functionality to apps or to the Finder.

In Extensions preferences, you can also select the items that you want to see in the Share menu, and select widgets you want to see in Today view in Notification Center. To open the preference pane, choose Apple menu > System Preferences, then click Extensions.

All

See all extensions you installed on your Mac. These are extensions created by third-party developers.

If the extension is a content extension that enables extra functionality in apps, you see an Actions checkbox below the extension. If it’s a Finder extension, you see a Finder checkbox. Select the checkbox to enable the extension.

Actions

See all content extensions installed on your Mac. Select a content extension to make it available in apps.

For example, if Markup is selected, you can draw on pictures and sign documents in Mail, TextEdit, and other apps.

Finder

(available only if you have Finder extensions installed)

See all Finder extensions installed on your Mac. Select a Finder extension to make it available in the Finder.

Photos

(available only if you have Photos extensions installed)

See all Photos extensions installed on your Mac. Select a Photos extension to make it available in Photos while editing photos.

Share Menu

Select the items that you want in the Share menu, and in the Social widget in Today view in Notification Center.

  • The Share menu is available in several apps, including Safari, Contacts, and the Finder. If an item is selected, but you don’t see it in an app’s Share menu, then you can’t use that item to share in that particular app.

  • Only items that allow posting or messaging can appear in the Social widget.

Today

Select widgets, such as Find My Friends, to show in Today view in Notification Center.

You can also show or hide widgets right in Today view.
