First, I'd like to say that I've looked upon many topics to search for an answer to this question and didn't find one that worked for me.
As it is written in the title, I'm on MacOs and when I try to launch Spotify, I just have a blank black screen juste like this (picture below). I tried to reinstall it many times (and emptying the caches) but it never changed something. I looked for a ru.mo in the app folder, and I don't have it (picture below too).
Please can someone help me ? This is the only way I have to add song to a playlist with friends.
Thanks a lot
