Last week my lab instructor started giving us introduction about linux and how to use CLI commands.
Anyway, he started insulting and joking about Mac OSX systems and how they are a joke systems. He said that, he used it for a week in my university department and he faced a problem, "you don't have a fully control on your machine; you always have to sudo to be a superuser -- that's why I use Windows" he said. "Mac is a linux based, Apple basically modified some codes, and mixed some to make this OS" he said.
I've been a Mac user since a kid, and I have learned that having a root access to do any daily work is a very bad and dangerous practice.
What do you guys think about what he said? did he really misunderstood Unix machines?
I'm not trying to prove or argue with anyone nor him, I just want to know if what he said could possibly be true? or he was just sharing his biased opinion?
What I meant is, if there is any difference between OSX, Linux and Windows authentication system?
