I was just thinking about this. Wrote the script, adding it now. It will show up as an update in Clutch and I'll post again here when it's ready (maybe in a few hours). Thanks!

Clutch v1.4 is now available!

- Clutch can now restart Transmission gracefully without using force-quit. This prevents you from losing your progress or torrent settings when Clutch has to restart Transmission. Enable this feature in Clutch for setup instructions.
- Added regex support for interface names. Be sure to use real regex and not shell glob. For example, enter utun.* instead of utun* if you want to use regex.
- Added a nice loading animation while Transmission is binding/unbinding
- Clutch now updates the list of interfaces each time you open the dropdown
- Fixed a bug where Transmission wouldn't restart if the bar menu was open
- Clutch now uses the new Mac OS hardened runtime
- Other minor bug fixes and performance improvements

Major portions of the app were rewritten to add the graceful quit option. Check out diff d3982b7 to see how much the code has changed!

You can update to the latest version by going to Clutch > Check for Updates...

New users, download the latest version of Clutch here: ...

Been testing this for over a week now on three different machines. Very good job. Thank you Sir!

Few observations:
- On 10.13 only the first security setting ("Accessibilty") is neccessary. The second button will open the "System Preferences" though, but there is - of course - no "Automation" setting found.
- On 10.14 the machine had to be restarted before the was showing up in the "Automation" settings.
- Couldn't see any "nice loading animation", but maybe I am just blind ;-)
- I am not a native speaker, so I was a little bit confused about the wording in the app. "Binding to [interface]" sounded to me like: "I am still in the process of completing the bind." I would have expected something like: "Bound to [interface]" when the process is complete. But again: I am not a native speaker.

Again: Terrific job!

Hi Harrison,

I have been using Clutch for a while with the connection to my VPN made by setting up the VPN in macOS's System Preferences/Network and since the VPN was always on the same interface, Clutch worked perfectly. Unfortunately, the VPN provider went out of business and my new provider uses Tunnelblick to connect. Apparently, Tunnelblick is rather popular, e.g., my ASUS router's VPN server uses it.

The problem that I am having is that the VPN tunnel is no longer always on the same interface, which means that when Tunnelblick connects and gets a difference interface, Transmission isn't allowed by Clutch to download. I know that this isn't really your problem and that supporting Clutch is an act of generosity. However, if you feel like fixing this problem, I would greatly appreciate it.
