I'm a developer, but it is more of a user-centric question.

How can one "unregister" a Finder Sync (or any other, presumably) OS X / macOS App Extension so that it disappears from System Preferences > Extensions?

I've removed the app that's hosting it (FinderSyncTest), but it still shows here:

How to remove 10.10 Application Extension

I found my extensions in:

/System/Library/PrivateFrameworks/ShareKit.framework/Versions/A/PlugIns

Delete FinderSyncTest.appex, restart Finder, and it should be gone.

  • Unfortunately, this is not the case here. – qdot Oct 24 '14 at 11:21
  • Try running "locate FinderSyncTest" from Terminal. Good chance you'll find where the extensions are located. – dejuknow Oct 24 '14 at 22:35
  • It didn't work for me for my project..... Any other way to find? – Anoop Vaidya Jul 27 '16 at 11:59

Another answer in addition to my previous one: if your extension is actually runnable (i.e.: it doesn't crash when started via System Preferences -> Extensions), find the extension in your Activity Monitor, double click the process, then go to the "Open Files and Ports" tab. You'll see the path of your extension listed.

Did you create this extension yourself?

I found that after creating, building, and testing an extension I created that there was some data that lives here:

/Users/*username*/Library/Developer/Xcode/DerivedData

that I needed to blow away to get the extension to "die"

    Yes I created my own, but it does't exist there, I removed all the files in DerivedData, but still see whole bunch of extensions. – Anoop Vaidya Jul 27 '16 at 12:00

I found my location via the "Open Files and Ports" location in Activity Monitor mentioned in the other answer.

This lead to the location:

/Users/USER/Library/Developer/Xcode/Archives/2018-10-09/MyApp 10-9-18, 9.35 PM.xcarchive/Products/Applications/MyApp.app/Contents/PlugIns/MyAppFinderSync.appex/Contents/MacOS/MyAppFinderSync

This archive was 10 days old and I'm not sure why it would have been running. I've been deleting my app since that date, and I believe the extension was being removed from System Preferences.

I deleted the archives in that location, and the app extension no longer runs (which it was doing before). However, it's still listed in System Preferences. Still looking for a way to fully delete.

Edit: I started running a new version of the container app, from /Applications/. About 10 minutes later, I went back to System Preferences and toggled the Extension on/off and back to on. This launched the new version of the Extension and everything appears to now be working normally.
