OpenSCToken does not get removed/unregistered

[mouse07410]

I am not sure if this problem manifests only if you build OpenSCToken from source and the copy of its executable is present somewhere on your system.

Config

MacOS Mojave 10.14.6, Xcode-11.3.1. Current master of OpenSC and OpenSCToken, OpenSSL_1_1_1-stable (1.0.2 is deprecated - it's time to move off it ;).

Symptoms

1. Build and install (from the OpenSCToken.dmg) OpenSCTokenApp.app.
2. Start it, observe it registering the extension. So far so good.
3. Insert the token, observe (e.g., via ps -ef | fgrep OpenSCToken) that OpenSCToken started.
4. Remove the token, uninstall OpenSC via /usr/local/bin/opensc-uninstall. Double-check that the /Applications/OpenSCTokenApp.app has been removed - delete it if it wasn't.
5. Insert the token - observe the extension started again.
6. Remove the token, kill the running extension, insert the token - observe the extension started again.

Workaround

• Determine what file the running extension was invoked from via

ps -ef | fgrep OpenSCToken

then

• Remove that file via

pluginkit -r /full/path/to/that/file

Now the extension is gone.

Proposed Solution

I don't know - maybe write a real uninstaller that would locate and remove/unregister this extension?
