Multiple Syncthing entries in Privacy & Security → Local Network

[acicovic]

Hello there,

I manage Syncthing with Homebrew and I'm on macOS Sequoia. By updating the software throughout time, I have now accumulated more than 15 syncthing entries in System Settings → Privacy & Security → Local Network.

Other software has been known to have this issue, like Chrome. There's an interesting writeup about how to reset this here, but I've been unable to do this since I've found no way to get Syncthing's bundle ID. What's certain is that just uninstalling Synching hasn't worked for me.

There's also an answer in the aforementioned Apple thread, which is quite interesting:

Later, in 2024, Apple upgraded that post to an official Tech Note: TN3179: Understanding local network privacy.

The first paragraph highlights special macOS Considerations. Right below that are "Build considerations". Here's where it gets interesting. Apple says:

Local network privacy uses your main executable UUID as part of its implementation. If your main executable has no UUID, or shares a UUID with other programs, local network privacy may behave weirdly. To fix that, make sure your main executable has a UUID and that it’s unique. For more about this, see TN3178: Checking for and resolving build UUID problems.

So the question here is twofold:

1. How to remove the existing duplicate entries, without getting into dangerous solutions like disabling SIP and deleting files, which can have unwanted side-effects?
2. Is there a way this can be fixed in Syncthing? If Syncthing has a particular implementation regarding its UUID, it seems that this could be the source of the issue.

Thank you!

Hm, wondering if I've posted this in the wrong place or not. This is because I'm using brew install syncthing, not brew install --cask syncthing-app which might be this repo.

No problem for posting this here, I have no problem with Syncthing.app but indeed the Chrome has problems for some reason. This is probably because macOS is sometimes bugged. I think there is not much we can do about it.

I have investigated, but the Syncthing macOS application and Syncthing executable have both an UUID. Not sure about the homebrew one.

Thank you for your time and response. Maybe switching to the cask could solve for not having new entries when I update.

Can't help but notice that from all the software I'm using, this only happens for Syncthing, but I'm fine with closing this if it's all we can do.
