To get the correct code for the macfuse kernel extension, I used this command (in normal boot mode): I tried all the other steps previously, and I was till getting the 'System Extension Blocked' dialog box when SIP was enabled.

usr/sbin/spctl kext-consent add 3T5GSNBU6W The step that I didn't see in the discussion here and was the key for me is (in Recovery mode): It seems like I got it working! I basically did something similar to what is described here (in the first comment by CodeBlazer):

It worked with SIP disabled, but not again after SIP is re-enabled. I am also getting 'System Extension Blocked', but no 'allow button' in system preferences. If you are highly pessimistic you could skip straight to step 8, but only a small (but significant) number of cases seem to need such extreme measures, so try the first steps first. you should now be able to mount your filesystem without error (but perhaps with a little dance of joy?).this time open System Preferences / Security and Approve the macFUSE Extension.attempt once more to mount your filesystem, and you will not be surprised to get the error 'System Extension Blocked'.restart macOS (without enabling System Integrity Protection).install macFUSE (while System Integrity Protection is disabled).restart macOS (as part of that process).IF you STILL get the error 'System Extension Blocked'.attempt once more to mount your filesystem.IF you get the error 'System Extension Blocked'.

attempt to mount your filesystem (using whatever software you have that relies on macFUSE).So the prevailing instructions coming from this thread seem to be: Is there a better way to test macfuse independent of sshfs? I tried running /Library/Filesystems/macfuse.fs/Contents/Resources/load_macfuse echo $?, which returns 1, indicating that the macfuse cannot be loaded, which makes me believe the issue is not related to sshfs. Have you checked in to see if your problem is mentioned there? Or if it's related to the specific command-line that you are calling in sshfs? If this issue only occurs with sshfs, perhaps it might be better to raise it there instead? Is your mac managed by a company who might have locked something down? Are there any side issues mentioned in there that might apply to you? Everyone else in this thread using macFUSE 4.2.0 on macOS 11.5 seems to find the reboot fixes their issue, so we need to find out what is different in your case.Īlthough no-one here says they are using sshfs, recent comments in issue #705 say that sshfs users got things working with 4.2.0 on Big Sur.
