FSKit (native and modern way to access users’ filesystems on macOS) support is now available in fuse-t on macOS 26+.
It means that temperamental NFS server workaround (to avoid kernel extensions - kext) is not needed any more.
After fixing some teething issues it looks like it is working now (needs v1.1.0a)
You have to install fuse-t from releases’ page (or via brew when v1.1.0a is released) and enable macOS FSKit support. Run fuse-t.app for instructions:
When enabled you should see:
Now to use it with rclone run:
$ rclone mount remote: /path/to/mountpoint -o "backend=fskit"
or to make it default edit /Library/Application Support/fuse-t/cfg/fuse-t.ini
If you try and have any issues with fuse-t then please report it directly on fuse-t github page instead of here. Alex Fishman (the software author) is very responsive and acts quickly on any bugs.
PS. macFUSE offers NFSKit support too - but it is not ready for any serious use yet.
