Hi John.
I have only just updated to El Capitan so I can't speak for Sierra.
ColorMunki Photo (software 1.2.1) works well under El Capitan and, for me, has produced good profiles.
If you've previously had v1.1.1 software installed on your system it is necessary to undertsake some file cleaning (this, from X-Rite). See this post:
ColorMunki Photo / Design – Monitor Profiles Too Dark on a Mac.
I have also tried the convoluted workaround (exporting PDFs from ColorMunki, importing them into Photoshop, printing them from Adobe Color Printer Utility, etc.) but there is a problem with this workaround under El Capitan, an sRGB profile gets inadvertently attached to the file. I haven't really got to the bottom of this yet but this is now largely academic since the new ColorMunki software gives every indication that it is printing correctly.
I hope this helps persuade you to give it a go under Sierra !
