 I can confirm that I can download the file from the Apple Developer site
 when I search for it and find it, but I can't download it by pasting the

 Once I get the file and place it in the proper location, the installation
 of {{{MacOSX10.13.sdk}}}  fails for me on 10.12 Sierra with:

 full log attached.

 I then downgraded {{{xar}}} from {{{xar @1.8.0.498_0}}}  to {{{xar
