Ok, I'm running a few tests this am, mind perhaps there are no OS-X OSProcessPlugin users out there? however thank you for taking the time to look into this.
First I went in and mangled MacOSProcessAccessor and MacProcess to remove the overrides for access to unix superclass logic then I prim failed the forksqueak prim call, and made the suggested change to UnixOSProcessAccessor>>canForwardExternalSignals
Testing
UnixProcessAccessorTestCase>testIsExecutableForUserInGroup accessor isExecutable: '/tmp/delete.me' forUser: 99999 inGroup: accessor primGetGid fails, but I'll note: -r-xr-x--- 1 johnmci wheel 0 Mar 4 13:47 /tmp/delete.me
testIsReadableForUserInGroup didn't look likely related to above testIsWriteableForUserInGroup didn't look likely related to above
testChDir for this accessor primGetCurrentWorkingDirectory returns /private/tmp on the mac
UnixProcessFileLockingtestCase wants to fork a headless squeak.... They all fail then...
UnixProcessFileLockTestcase They all RUN (GREEN)
UnixProcessTestCase 5 run, 13 error because they all attempt to fork a squeak vm.
Likely I should look at the ancient code for headless squeak, if there is any visible demand?

ok, after some clues from David I built a mostly broken unix vm, however it was enough to build a OSProcessPlugin as a side effect.
In testing I see that calling primitiveForkSqueakWithoutSigHandler crashes things, I'll suspect forking the carbon vm is a no no.
Hi John,
If you have a chance, could you please try something for me? Change the method UnixOSProcessAccessor>>canForwardExternalSignals to answer false, then save your image and restart.
