what OS you use?

I know it is very basic, but Ubuntu 20.04...

I actually use Windows and ever linux

I wanted to change the OS and switch to linux but since I have no problem with windows, I'm keeping it

I use Windows for normal things and development, and then Parrot OS for most pentesting and HackTheBox

I use the wonderful (but shitty in the same time) windows 10 OS

Windows 10 and Remote Desktop connection to a rented windows 2016 server machine

Windows for work, Mac for personal - i find creating and producing on macs to be easier but just for work functionality and compatibility windows is easier

mac for work, windows at home!

Mainly use Windows but I use Linux as well as MacOS equally for app support.

Any Linux distro, preferably Debian
