I tried on 2 different macs imac and MBP both with Sierra, and it worked fine.
I have 2.78a though, the latest version.
Can you download 2.78a and try if it works ?
Also if it can not write the crash log, maybe try to run it as root or sudo just for this occasion

This is unclear whether this is same issue even? Original report was about crash when running blender in background mode.

Also, you are launching blender in admin mode (assuming sudo means more or less the same thing as under linux), why?

In any case, we'll need some dev with OSX access to try and reproduce that with a debug build…

I think the core bug in this report is the same as I'm experiencing, and that is the OSX version is not writing to crash.txt like it is supposed to from creator_signals.c (code below)
I launched Blender in both admin mode and regular mode. the reason for trying sudo was at the request of Olivier Amrein above.

FILE *fp;
	char header[512];
	wmWindowManager *wm = G.main->wm.first;

	char fname[FILE_MAX];

	if (!G.main->name[0]) {
		BLI_join_dirfile(fname, sizeof(fname), BKE_tempdir_base(), "blender.crash.txt");
	}
	else {
		BLI_join_dirfile(fname, sizeof(fname), BKE_tempdir_base(), BLI_path_basename(G.main->name));
		BLI_replace_extension(fname, sizeof(fname), ".crash.txt");
	}

Okay, I see what you are saying.
I was reading the info, not the title.
I will close this and open a new report.
