macOS: test fuse-t
https://www.fuse-t.org should be tested by a macOS user whether it works with borg:
- using llfuse
- using pyfuse3
Besides practical testing one should also run borg's automated testsuite.

Came to post the same. Will try it out. May help us revive those mount tests. And even the Homebrew formulas.
It would also help if the developer of fuse-t actually open sources it.
Currently there is not much to see in that github repo.
Fuse-T developer said it will eventually release source code when the code will be in good state. We (I) can certainely test it, it's just a matter of including the right lib. But before getting stuff more "official", I really suggest waiting for OSS release and code review, since it could break all the shiny security put in place by borg.
It appears not to work. Usingborg 1.2.3 from the borgbackup/tap/borgbackup-fuse tap.

borg mount not available: no FUSE support, BORG_FUSE_IMPL=pyfuse3,llfuse.
@gorbypark hmm, the error msg is the same as if neither llfuse nor pyfuse3 is installed.
Maybe first get it working with another fuse implementation and then try fuse-t again.

Everything works when macfuse is installed + the kernel extension is enabled. Fuse-t is correctly installed as I use it for sshfs.
When macfuse is installed (but kernel extensions is not enabled) and fuse-t also installed, I receive
borg mount borgbackups borgmount
Enter passphrase for key /Users/gorby/borgbackups:
mount_macfuse: the file system is not available (1)
If I uninstall macfuse, leaving only fuse-t, I receive what I got above,
borg mount borgbackups borgmount

Can you just try from a python interpreter:
import llfuse
import pyfuse3
Does this work or is there some exception?

It seems I do not have those available. I'm not an expert at python, but I believe during the installation of Borg, I saw an env was being used to install some python dependencies? Is it possible I need to activate that environment? I guess it doesn't really make sense to have to run Borg in a specific environment, though. I will try and install llfuse and pyfuse3 globally and see what happens.

Ok, so it appears that both llfuse and pyfuse3 rely on libfuse being installed, which as far as I can tell is not available on macOS. I am not sure if macFuse is supplying the headers for libfuse allowing it to work?
With macfuse uninstalled, both pip install llfuse or pip install pyfuse3 fail with a similar error. Installing macfuse (but not activating the kernel extensions) allows pip install llfuse to install. Although, importing llfuse throws this error

AFAIK, macfuse is still only supporting fuse2 (not fuse3), so pyfuse3 can not work for macfuse.

Ok, kinda makes sense, it seems like llfuse is for fuse2, so installing macfuse is giving headers for fuse2. Although, fuse-t's website is saying
Drop-in replacement for osxfuse (https://osxfuse.github.io/). API headers in libfuse are identical so there's no need to change anything in the filesystem implementation. The APIs are compatible with macfuse but differ from the Linux version of libfuse because the macfuse project was not updated in sync with the corresponding Linux version
It seems like fuse-t should be compatible with macfuse, but I'm not quite sure if I'm interpreting that correctly.
@gorbypark maybe you could ask the fuse-t author if they know what's missing or how to fix.
One year later and the fuse-t project does still not seem to be going open source. Guess that makes it way less interesting for borg users and thus I am closing this.
