Hello,
I've just installed gcsf on macOS and unfortunately it wouldn't mount.
$ gcsf mount gd -s session
ERROR fuse::session > Failed to unmount /Users/badt/gd: Resource busy (os error 16)
$ sudo diskutil umount force gd
Unmount successful for gd
—is the procedure I have to go through to free up /Users/badt/gd after ^C out of gcsf.
This is definitely not an osxfuse issue, because sshfs works just fine here.
