For me it has to be macOS (Unix)

OS/2 Warp

I’m a Linux and Windows user, but it’s the last one that I prefer. It works without fuss.

This is tricky….
In the past I liked OS/2 Warp and AIX very much.

Nowadays I work mostly with RHEL and Windows Server.

grew up on MSDOS > Windows 3.1 > WINNT 3.51 > Windows 95 > Windows 2000 > Windows 7 > Windows 8 > Windows 10 and now on Windows 11. But I use Mac Os on work’s laptop ...hate it

OS/2 Warp 4, yup I played with that two. That was an IBM thing I believe but they dumped it.

FreeBSD, for security OpenBSD. As for the Linux distros, debian, and debian based distros. I did do some slackware for a while because I was attempting to get into the cool crowd but.. did not happen. 

Have had some fun with ReactOS as well. https://reactos.org/

What no Windows NT?? :) 

I got my one and only MSCE on Windows NT and then Luke Skywalker convinced me to go over to the bright side of the Force! :)

I think that that used to be on a FreeBSD kernel but I believe they went over to their own home grown a few releases back. 

Yes, IBM dumped it. But it is still around as community project 

Preferred OS for working (as workstation) OSX!

Preferred OS for Servers, Linux!

In my personal computer I will ever prefer Windows.

I'm a productivity lover and all things need work fast for me. So, I even don't like to think about the idea about apps that only runs on Windows ecosystem. Open a VM only to runs this kind of stuff is a horrible option...  

For the most part I am a Windows guy but lately been learning more about Linux so getting used to it.

Does iOS count?
If I could, I would do anything on my phone 

Like a real GEN Z user 

Unfortunately, I‘m Gen Y

I don’t really know if I have a “favorite” but I prefer Windows, because I’ve been using it for so many years at both work and home.

I can use Mac OS, Linux, others, but if I was to choose, I always go Windows.

While I work mostly with Windows, I would go with Linux. I used to run openSUSE at home but am slowly switching to Ubuntu.

Right tool for the job…..Windows in most cases for me, but now as I get the feeling that linux is gonna be my favorite for repo/proxy servers really soon….as soon as I can start playing with them.  :-)

Fedora on laptop and RHEL on servers, yes i’m from Linux world .I got lost on the Windows World with veeam, still dreaming a vbr on linux full deployed and managed by ansible.

Someday maybe….they’re making some motions that direction with the Linux Proxy’s an Repo’s.

It will be available when it will be a ready, i will say . I am convinced that the emergence of hyperscalers has something to do with the new trajectory with veeam on linux.
