Comment (by michaelld):

 Thank you @VinDuv for the continued sleuthing and information. I will get
 there sooner or later and work through what you're found & the current
 patches, and we can work out a better solution. Thanks @kencu for keeping
 the discussion going!

 Sorry this is taking so long! My actual W2 "work" is keeping me quite busy
 at the moment. The 10.13 boot is still updating ... not the fastest Mac in
 the world & all those !@#$ GCC and Clang compilers take quite some time to
 build. Thanks for your patience!
