meek and moat are broken on macOS 10.9 with the switch to Go 1.12
moat on macOS 10.9 one gets
dyld: Symbol not found: _unlinkat Referenced from: .../Tor Browser.app/Contents/MacOS/./Tor/PluggableTransports/meek-client-torbrowser Expected in: flat namespace
and the pluggable transport being non-functional. As I wrote in comment:36:ticket:30126:
I suspect the underlying problem is a change in Go 1.12 where Go is starting to use
libSystem.dylib etc. for syscalls: https://github.com/golang/go/issues/17490. (The mac-ports folks had to work around that e.g. in https://trac.macports.org/ticket/58138).
