@Gaby I have the same situation as you. Mac as primary personal use but I’ve also got a windows laptop (that I game and work on) and a Linux tower. Apps that play nice on these three are a real treat. Just wanted to mention that there’s a plug-in for obsidian called Longform that offers focused project structure similar to Ulysses, and if you’re not sure about obsidian there’s another great note taking app called Zettlr which I also really rate.
