@Karl (Laptop) in answer to your question - that manifest file is related to the hops config, but it's not the thing which set it.
Drilling in to find that config file on an installer version of Patchwork will require you to know where and how you system installed applications (mac/ linux). In mac I think applications are just folders and you might be able to see things ....

tl;dr anything is possible. What do you to achieve exactly?
