Wait, Why macOS Sequoia 15.2 and Not 15.0?

When Sequoia 15.0 shipped, the familiar checkbox list used to enable Finder Extensions in System Settings completely disappeared. The only way users could enable Finder extensions on macOS 15.0 was via the command line (Terminal) or by installing third party apps. Apple acknowledged that this was a bug in the macOS operating system and fixed it in version 15.2. If you are running on a version of macOS Sequoia prior to 15.2, please update your operating system to restore Finder Extension functionality to System Settings.

A Brief Reminder of What Finder Extensions Are:

Finder extensions (sometimes called Finder Sync extensions) let apps bolt extra features onto the Finder like status-badge icons (✔︎/⚠︎), custom toolbar buttons, or right-click actions. They ship inside some of the apps you install but stay disabled until you turn them on in System Settings. 

Updated Instructions for macOS 15.2 and Later

1. Open System Settings.
2. In the sidebar choose General → Login Items & Extensions.
3. Click File Providers (you may only see it if at least one app on your Mac contains a Finder extension).
4. Turn on the toggle switch next to the extension’s name to enable it.

Note: Don’t get confused by the Finder section under “Login Items & Extensions”

If you open System Settings and go to General → Login Items & Extensions, you’ll notice that there is a “Finder” section right above the “File Providers” section. This area is for enabling what used to be called Finder “Quick Actions” (although the text in System Settings now suddenly calls Finder Quick Actions Finder Extensions, which is confusing). If you are looking to enable or disable a Finder extension for an app you downloaded from the Mac App Store or from a developer’s website, you want to go to the “File Providers” section.

Quick Summary: To Enable Finder Extensions on macOS Sequoia
