Brew install not working on MacOS

[lodenrogue]

brew install sshfs gives this error:

libfuse: Linux is required for this software

Full output of the brew install command:

I'm on M2 Sonoma.

I ran into this same issue today. It's a homebrew problem, though, not a sshfs issue. Here's the commit to homebrew that added the depends_on :linux that's leading to our error message:
Homebrew/homebrew-core@c5ffc55

There used to be a message describing their reasoning (the formula being unusable without closed-source macFUSE), but that was also removed with this commit. Here's the text that used to be shown when attempting to install on MacOS:

       The reasons for disabling this formula can be found here:
          https://github.com/Homebrew/homebrew-core/pull/64491
        An external tap may provide a replacement formula. See:
          https://docs.brew.sh/Interesting-Taps-and-Forks

@lodenrogue I followed the "Interesting Taps and Forks" link from that deleted text and there's a link to gromgit/fuse. Following that to https://github.com/gromgit/homebrew-fuse, I followed the instructions to install with this command:
brew install gromgit/fuse/sshfs-mac
and it worked great.

Thanks I'll check it out @kslattery

Perhaps it would be easier for everyone if the releases included pre-compiled binary files as well? Similar to what the sshs team has done, for example: https://github.com/quantumsheep/sshs/releases/tag/4.4.1

[bfleischer]

A precompiled universal binary (Apple Silicon and Intel) of SSHFS 2.10 is available on https://macfuse.io and https://github.com/libfuse/sshfs/releases/tag/sshfs-2.10.

As of writing this, version 2.10 is the latest version of SSHFS that will run on macOS. SSHFS 3.x requires libfuse 3 which has not been ported to macOS. yet

Thanks for posting. I have the same issue on M4 Pro and macOS 15.3 Sequoia.

@bfleischer seems to be correct. There is a raised issue for this on libefuse, but unfortunately there doesn't seem to be a clear path forward. Although I work as a software engineer, I must embarrassingly admit that I don't follow the discussion.

The workaround of trying to install macfuse seems to require the enablement of "system extension". Is this truly safe?

For context, it's as safe as installing a kernel-mode driver on Windows. The difference is on macOS the ability to install non-apple kernel-mode drivers requires you to explicitly allow it by following a few steps.

[bfleischer]

Since version 4.10.0, macFUSE ships with the latest versions of libfuse2 and libfuse3. This means the latest version of SSHFS 3 works on macOS, too. Precompiled binaries are available from the releases section of the SSHFS repository or https://macfuse.io/.

I'm new to this stuff. After read through the post I'm still don't know if I can still install macFUSE via Homebrew then install sshfs also via Homebrew too. Or I need to install from .dmg file? Could someone help me with it!

I installed macFUSE via Homebrew already, and then tried to install sshfs but received this output:

➜  mkdocs brew install sshfs
==> Fetching downloads for: sshfs
sshfs: Linux is required for this software.
libfuse: Linux is required for this software.
Error: sshfs: Unsatisfied requirements failed this build.
==> No outdated dependents to upgrade!

This is my macFUSE version:

➜  mkdocs brew list macfuse
==> Pkg
Extras/macFUSE 4.10.2.pkg (Pkg)
==> Postflight Block
postflight (Postflight Block)

@minhnguyen1908 bfleischer said above that MacFuse 4.10+ ships with sshfs. I don't know if the Homebrew folks keep sshfs bundled, though. I do know that the MacFuse install page https://github.com/macfuse/macfuse/wiki/Getting-Started says that they do not control the version offered in package managers (like Homebrew), and they suggest that you download the binaries directly from https://macfuse.io/ or https://github.com/macfuse/macfuse/releases .
You might just try running MacFuse as-is - maybe Homebrew has been updated to use the MacFuse-included sshfs (which seems unlikely given the reasons they had for removing it in the first place). If it doesn't work, though, I'd suggest uninstalling the brew version of MacFuse and installing the version offered on macfuse.io.
