I believe the issue here is that the filesystem that the repo is on does not
support exclusive file locking. The solution here is to not use filesystems
that don't support exclusive file-locking. I don't know any of the details
of how the MAC <-> MAC network file sharing is implemented, but I think you
are out of luck using that file access method. Stick to local drives or
perhaps switch to NFS or something like that.
