Note that mapping to a directory path, instead of a drive letter, does not suffer from the same limitations. +## Mounting on macOS + +Mounting on macOS can be done either via [macFUSE](https://osxfuse.github.io/) +(also known as osxfuse) or [FUSE-T](https://www.fuse-t.org/). macFUSE is a traditional +FUSE driver utilizing a macOS kernel extension (kext). FUSE-T is an alternative FUSE system +which "mounts" via an NFSv4 local server. + +### FUSE-T Limitations, Caveats, and Notes + +There are some limitations, caveats, and notes about how it works. These are current as +of FUSE-T version 1.0.14. + +#### ModTime update on read + +As per the [FUSE-T wiki](https://github.com/macos-fuse-t/fuse-t/wiki#caveats): + +> File access and modification times cannot be set separately as it seems to be an +> issue with the NFS client which always modifies both. Can be reproduced with +> 'touch -m' and 'touch -a' commands + +This means that viewing files with various tools, notably macOS Finder, will cause rlcone +to update the modification time of the file. This may make rclone upload a full new copy +of the file. + +#### Unicode Normalization + +Rclone includes flags for unicode normalization with macFUSE that should be updated +for FUSE-T. See [this forum post](https://forum.rclone.org/t/some-unicode-forms-break-mount-on-macos-with-fuse-t/36403) +and [FUSE-T issue #16](https://github.com/macos-fuse-t/fuse-t/issues/16).
