external diff from log selected window

[Robin Weiss]

Trying to use an external diff tool from within the "log selected" window but option is not available. Have set up my external diff tool and it works without issue.

In windows implementation of sourcetree we get the following from the log window:

In mac we get the following in the log window:

Also, the external diff menu option from the actions menu is disabled when in this view.

Workaround clearly is to open both of the commits and then toss them into my diff tool. What is the best way to send two arbitrary commits of a specific file into an external diff tool within sourcetree on mac?

SourceTree does not allow you to diff arbitrary commits with each other on any OS. In Windows (where you appear to have the option), you'll find that actually using the external diff will compare the commit you right-clicked on (regardless of other commits in your selection) with your working copy.

The Mac interface is probably slightly better in this respect, as it doesn't imply that you are using a feature that isn't there.
