I have a very interesting question. I am aware of the rules regarding unofficial clients, but what if I run the official client through wine. Basically it allows you to run any Windows app on macOS and Linux, with a lot of tinkering.
I eventually got the official client (downloaded from Steam) running on my mid-2014 Macbook Pro with some ok performance and working microphone. Could this get me banned, even with the latest official client? (sorry if this is the wrong place to ask, this is my first post here.)
