I have it set as a folder action, and I'm not sure if the syntax has changed with the new version of FileBot, if I need to do a modified version of the script with Yosemite or what.
I'm using it to rename TV shows that deluge downloads (I tried getting the scripts to work with that, but it never worked for me in the past so I ended up going with folder actions.)
Here is my script as I had it working before:
/Applications/Filebot.app/Contents/MacOS/filebot -rename ~/Downloads --output ~/Downloads/TV\ Shows --format "{n} - {s00e00} - {t}" --db thetvdb -non-strict --def artwork=y -r

Would appreciate any light anyone is able to shine on this.
Thank you in advance.
