Taking a closer look the problem is obvious -- the method coroutine_start is only defined in two #ifdef blocks, one for WINDOWSand one for LINUX.

I tried duplicating the Linux implementation wrapping it in #ifdef __APPLE__

but I got he following errors compiling hotspot/src/share/vm/runtime/signature.cpp:
