What's wrong with open process? The *only* difference between open
process
on macOS compared to Linux (and Windows) is that if you try and open
process
an app-bundle (i.e. something ending with '.app') it will do the same as
launch (as .app bundles aren't executables).
The installer uses open (elevated) process to communicate with an
instance
of itself with elevated permissions. You can see the code for that here:
<https://github.com/livecode/livecode/blob/develop/builder/installer_utilities.livecodescript>
The key routines are installerRun and installerMonitor (the latter is
used
to poll every 20 milliseconds to check if the child process has anything
to
say).
Warmest Regards,
Mark.
