Nah it was a while back. IIRC there were multiple sources, but I don’t remember any of them 🙃
Though, I don’t really remember the details either. Maybe it was OS specific? I know there was a dodgy FUSE implementation out there for macOS at some point, and Cryptomator depends mounts its local drive with FUSE. I use macOS and NixOS, so it coulda been that.
Wow, I can’t believe I almost forgot about netbooks
