Using Meld as External Diff and Merge Tool in Source tree in Mac

I am trying to set up Meld as the external diff and merge tool in Source tree on my Mac laptop. I put down Meld's file path on "Command" as shown in image below. However, when I right click a file and do external diff, the meld GUI just launches but it is not displaying the file or the diffs at all. Am I missing something in the Argument field ? 

Second Question: How do I do different kinds of diff (see below) in Sourcetree ? 


git diff --cached
git diff 
git diff HEAD

I had to put PATH=/usr/local/bin:$PATH meld in the Diff command field. I have $LOCAL $REMOTES for the arguments.

I haven't set up merge, but it'll be similar I imagine.

The small text at the bottom of that screen explains the variables you can use in "Arguments".

This page explains the arguments that Meld expects:

Yes, I saw those variables but I am not sure how to use them . Can you give me an example please ?

Please give an example. Or would you like the 10 page stack trace I'm getting?

I use meld as a Visual Diff Tool. I don't think it can be used as a Merge Tool (which is 4-way). My arguments for the diff tool are: $BASE $REMOTE $LOCAL

If you prefer the files to be displayed in a different order in meld, change the order of the arguments.

Did you get this working? If so any chance you could update your question with the configuration you've used?
