FUSE for macOS is no longer open source
By the way if you are searching for some cross-platform FUSE-like alternative for a project I encourage you to try WebDAV if something else is your bottleneck.<p>It saved me some headaches from bundling an installer for macFUSE or Dokan's blue screens in the past. There are server implementations and also FUSE wrappers on GitHub. It's not perfect but worth a try. And it's supported directly by many OS.
