Comment (by dcf):

 Replying to [comment:1 gk]:
 > I suspect fixing that problem properly is a ton of work which seems not
 really justified at the moment given that we did not hear a single
 complaint about this problem so far and 10.9 is rather old. Not sure what
 is causing this syscall but maybe we could avoid that instead as a
 workaround?

 I suppose this is a problem not only with the meek from meek.git, but also
 when using meek_lite with obfs4proxy (#29430)? Or does obfs4proxy somehow
 avoid using the problematic `_unlinkat` symbol? If the latter is the case,
 then #29430 would seem to solve it.

 According to https://github.com/golang/go/wiki/Darwin, OS X 10.9 is not
 supported past Go 1.10.8.
