If you want to use Xcode's FileMerge as your git mergetool, this is how you set it up.
Raw
gistfile1.sh
# Tell system when Xcode utilities live:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
# Set "opendiff" as the default mergetool globally:
git config --global merge.tool opendiff
# Then, when git tells you that there is a conflict, you can run `git mergetool` and
# it will open XCode's mergetool (like in the question's screenshot) and you can work through the conflict.
