FUSE-T is a kext-less implementation of FUSE for macOS that uses NFS v4 local server instead of a kernel extension.
The main motivation for this project is to replace macfuse that implements its own kext to make fuse work. With each version of macOS it’s getting harder and harder to load kernel extensions. Apple strongly discourages it and, for this reason, software distributions that include macfuse are very difficult to install.
With Apple locking down macOS more and more, developers have to resort to ingenious solutions to maintain the same level of functionality as before. This is an example of that.
