OS X apps installed via Homebrew Cask can have a "zap" command defined that will automate a deep uninstall:

`brew cask zap <app_name>`

It isn't an acceptable answer for the average Mac user, but it at least solves the issue for a subset of users.

The majority of MacPorts programs I installed over the years uninstalled cleanly.

Also I could be wrong but isn't/wasn't the whole "fat binaries + static binaries + app binary and its associated assets live in a magic folder that the OS-X GUI displays as 'the app' + other past Mac app trickery such as resource forks etc" all meant to make both app install and UN-install painless and easy ?

I know and used a few commercial apps that were a damn pain to scrub completely off the Macs I owned but that was expensive proprietary commercial software that felt the need to take my money and also saddle me with DRM to enforce their licensing.

Not all Mac apps are of the "drag to your /Applications folder" variety. Some still come with an installer they expect you to run, and prompt you for admin rights.

Probably inspired by AppZapper which does a great job of addressing the problem
