What is the difference between OS Linux and OS X (Mac)?

Question

linux

We will assume that the question is from a teapot who has been working on Windows all his life, very rarely did something in the console under *nix (following tutorials to set something up), so I have little idea of ​​​​the difference. I deal with OS X, but besides using only GUI.
Suppose I want to get to know the world of the console and Linux in general better, in order to be able to set up the environment, install my applications on the server, etc., in general, the minimum set of things that it is very desirable for a backend developer (not a system administrator) to know.
The question is: if OS X and Linux are more or less close relatives in their roots, even if there are differences (which are included in each individual version of Linux), what are the differences between these two systems?
For example: if I leave the choice on OS X,Will it be possible to apply (impose) the knowledge of commands and the device of the system if I have a Linux distributor in front of me . The soul lies in using macOS, but at the same time, the goal, I repeat, is to know a little Linux in order to be able to configure the environment, etc.
Or, after all, OS X is one thing, and Linux is another, and each needs to be known separately. In this case, I will choose Linux, because. this is an important point that you need (useful) to know, because http servers, databases, VPNs, other applications work on it + this is a plus when applying for a job . And Makosi's knowledge is already a matter of personal preference, where it is more convenient to work (at the moment I work mostly in Windows, but I want to move in the near future, in connection with which this question was born).
I hope they understand me. Ready to clarify if something I wrote is unclear in the question. Thank you.
upd: in the meantime, I googled a bit and found for example the following:

Need to differentiate the points of views:
From the shell-users point of view here is no big differences. OS X is a fully certified Unix operating system, so it's command line is fully compliant with Unix standards and POSIX. You have terminal with shell, all shell commands (BSD style), you can install eg macports for GNU-versions of commands. eg the bundled sed is without --long argumnets, when you install macports you will get gsed - the GNU version. You have a common directory structure as /bin /sbin /usr/bin .etc..

Answer 1

Linux has nothing to do with OS X other than POSIX.
Bash is the same here and there, but the firewall is already completely different. This is so, for example.
If you are interested in servers and stuff, then OS X will not replace Linux. Everything is completely different.
If you find a file, or run through the contents of a text document, then there is no difference.

Answer 2

In fact, you are simply in vain resting on one system.
Even when working in Linux, it is better to raise the server for the backend not in the main system, but in a virtual machine (Vagrant for help). This server, of course, should be on Linux - you are unlikely to ever need hosting for Windows or Macos. But what will be the main system - here "choose to taste."
Makosi, IMHO, has only two pluses: a more polished (but also less customizable) DE and the existence of proprietary programs like Photoshop for it. I personally don’t need the second, but the first only interferes - so the choice is obvious ...

Answer 3

to be able to set up the environment, install my applications on the server

Install server OS.
In virtual.
As a rule, these are Linux, FreeBSD, Solaris.
But not MacOSX. For example, there is another autostart. And a bunch of stuff. small things
MacOSX and Linux have only Posix, world utilities and shell in common.
But this is already perfectly supported in Windows 10 (Ubuntu Linux Subsystem on Windows) without virtual machines.

Answer 4

If you are on windows, then from 10k ubuntu can be installed in a couple of clicks right in Windows, or in a scribe, which is more than enough for development and familiarization, and makos is about show-off paid rethought Linux with cute animations 10 years ago it was probably cool, but now most they put Windows on a poppy and get both show-offs and all the Windows software.

Answer 5

It will work 100%, but only at a bus frequency of 1333 Mhz.
