macos – Macbook and Homebrew safety situation

I am a brand new Mac person and I am attempting to be taught a little bit of all the pieces (terminal instructions and many others.)

Presently, I want to put in homebrew with a purpose to set up pyenv (from which I can obtain varied variations of Python after which use pip straight for the libraries) however I’ve doubts about safety.

I learn that I may set up pyenv straight however I wish to have homebrew in case I want to put in different packages sooner or later.

I’ve learn in varied posts that putting in Homebrew entails altering folder permissions which may result in safety flaws, how can I keep away from these issues? I learn {that a} very helpful technique is to create a brand new person simply to put in Homebrew and obtain the packages from there (the posts are Bettering safety of homebrew set up (possession of /usr/native) and Are my permissions for /usr/native/ appropriate?).

I do not perceive very nicely do it, may somebody assist me? Ought to the person account created be native or administrator? and do I’ve to reset the unique permissions from the homebrew account after they’ve modified? Would utilizing pip or pyenv have issues this manner?

To be extra exact, my query is how can I set up Homebrew and have safety?
