[HELP] General Mac OS usage questions :)

[Selur]

Thought I open a thread where I post general Mac OS questions in the hope some of the Mac users can help.

First question:
Is there a "build-in" uninstall somewhere in Mac OS or is it still necessary to remove the content of pkg files manually ?

iirc one can do it manually by using:

pkgutil --pkgs | grep Hybrid

to find the Hybrid packages

pkgutil --pkg-info the-package-name.pkg

to get the files theat were installed

pkgutil --only-files --files the-package-name.pkg | tr '\n' '\0' | xargs -n 1 -0 sudo rm -f
pkgutil --only-dirs --files the-package-name.pkg | tail -r | tr '\n' '\0' | xargs -n 1 -0 sudo rmdir

to remove the files.

sudo pkgutil --forget the-package-name.pkg

to remove the package info.

so another related question:
In case there is no "build-in" uninstall graphical user interface in Mac OS, is there some recommend (no limited to X uninstalls) freeware to do the job?
