How to change Extensions settings on Mac?

Whether you want to turn on or off the extensions for Apple and third-party applications on Mac, edit the extensions listed in the Share menu, or add extensions for apps, Finder, and the Touch Bar, this part covers.

Options available in Extensions:

Added extensions: These are extensions created by third-party developers. You may see Actions, Finder, Sharing, and other tick boxes below the app extensions. For example, I installed the iBoysoft MagicMenu, a right-click enhancer, and there is a Finder extensions tickbox, I need to select it so that I can access the iBoysoft MagicMenu's feature via the Finder context menu.

Actions: These are content extensions installed on your Mac. If you select the Markup, it enables you to annotate and draw on PDF documents and images in apps such as Mail, TextEdit, or Preview. See How to use the Markup tool for Mac?

Finder Extensions: Finder extensions installed on your Mac. If you want to make a certain extension such as iCloud Drive available in the Finder, just check the box below it.

Photos editing: Photos extensions installed on your Mac, such as Markup. After you select the Photos extension, it will be available in Photos while editing photos.

Quick Look: Quick Look extensions installed on your Mac, such as Mail. If you enabled the Quick Look extensions for apps like Mail, you can quick look an item on Mac without opening it.

Sharing: Select the sharing extensions such as Copy Link, Notes, and Add to Photos so that they are available from the Share button in the Finder and in many Mac apps.

Note: You can't uncheck default extensions like Mail and AirDrop. If an extension selected in the list is not available in the Share menu, it indicates the item you selected can't be shared using that extension. For example, you can use AirDrop to share a web page in Safari, but not selected text.

Finder: Enable extensions you want to access from the Quick Actions menu on the desktop and in the Finder and the Finder Preview pane.

Touch Bar: If your Mac has a Touch Bar and you set Touch Bar options to show Quick Actions or added a Quick Action button to the Touch Bar, select the extensions you want to access from.
