: For that reason the latest lmtx installer now (for the time being) also includes the luatex binary (plus mkiv files needed) so that one can install lmtx and run both engines. Instead of the --luatex switch one can also force the engine in the usual way with "% engine=luatex" at the top line of the source file (but no pdftex and xetex in this installer).
I updated LMTX on MacOSX 10.13 today. The luatex binary in not executable, thus when I run axel$ context --luatex --version mtx-context | redirect luametatex -> luatex: luatex --luaonly "/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context --luatex --version --redirected mtx-context | ConTeXt Process Management 1.02 mtx-context | mtx-context | main context file: /Volumes/Macintosh HD/usr/local/texlive/2019/texmf-dist/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2019.03.21 21:39 it picks up the TeX-Live version. after I axel$ chmod 744 luatex I get the correct version: axel$ context --luatex --version mtx-context | redirect luametatex -> luatex: luatex --luaonly "/usr/local/texlive/LMTX/tex/texmf-osx-64/bin/mtxrun.lua" --script mtx-context --luatex --version --redirected mtx-context | ConTeXt Process Management 1.03 mtx-context | mtx-context | main context file: /Volumes/Macintosh HD/usr/local/texlive/LMTX/tex/texmf-context/tex/context/base/mkiv/context.mkiv mtx-context | current version: 2020.04.03 10:31 mtx-context | main context file: /Volumes/Macintosh HD/usr/local/texlive/LMTX/tex/texmf-context/tex/context/base/mkiv/context.mkxl mtx-context | current version: 2020.04.03 10:31 Greetings Axel
