How to modify a app installation on a Mac?

How can I modify (meaning go back to the setup wizard and change the settings of a specific app, or is there a better way to do that) an app so I could put the directory in a different PATH or change any of the app's settings?

BTW

I am asking this question to solve another question on Super User.

NOTE: I am a Windows user with only a few experiences with a MacBook.

Solution 1:

There's no common/standard way to do what you're looking for.

Mac apps rarely use installers any more. Being prompted for install-time options is rare.

It sounds like you're specifically interested in Vscode. Microsoft distributes Vscode for macOS as simply the app itself, zipped. Once you unzip it you drag and drop it wherever you want it to live on your filesystem, and that's it. It doesn't have install-time options or a real setup assistant. It has some "getting started" screens that walk you through customizing minor preferences like syntax coloring schemes and stuff, but nothing that would relate to that other question about the multiple running instances.
