Couldn't find Transmission's web interface files!
Users: to tell Transmission where to look, set the TRANSMISSION_WEB_HOME environment variable to the folder where the web interface's index.html is located.
Package Builders: to set a custom default at compile time, #define PACKAGE_DATA_DIR in libtransmission/platform.c or tweak tr_getClutchDir() by hand.

Yep, this is likely because you're running a build that you made yourself, rather than one that was installed with an installer. That's OK.

The way I usually get around this is to set an environment variable TRANSMISSION_WEB_HOME set to /path/to/where/you/git/cloned.../transmission/web/public_html

If you prefer, you can also hardcode that path in tr_getClutchDir().

No, the assembly was taken from here:

Any solution to this ongoing problem with those trunk builds?
../Contents/Resources/web/public_html/index.html exists inside the .app

I had the same issue and then worked out (or didn't?) that you have to install the Transmission CLI app as well, which i did with homebrew, then it was just a matter of brew install transmission-cli and going from there.

'brew services start transmission-cli' open the web interface from the Transmission preferences window. And then 'brew services stop transmission-cli' if you want it to stop running in the background.

Line 401 in platform.cc reads:
#ifdef BUILD_MAC_CLIENT /* on Mac, look in the Application Support folder first, then in the app bundle. */
so I tried creating a symbolic link in ~/Library/Application Support/Transmission/ for both the public_html and the web folders pointing to originals in the app bundle. But the web interface still failed to find its files. I also tried adding symbolic links in /usr/local/share/transmission/ with no effect.
