To steer away people looking for a solution for shares, not matter if it is osxfs or something else (at least it should work), i created this discussion/solution here: Alternatives to OSXFS / performant shares under OSX - so this topic can stay on “when/how to fix osxfs specifically”.@olat this is also for your (docker-sync)
Hopefully this is the last attempt to keep it on topic, i am aware that i am not free of guilt here, sorry.
