I have re-installed the latest luametatex (macOS) following the directions on the wiki (https://wiki.contextgarden.net/Installing_ConTeXt_LMTX_on_MacOS)

Though 
luametatex --version 
mtxrun --generate
are successful,
context --version
context --make --all
gets
mtxrun          | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua'
 and luatools --generate
gets
zsh: command not found: luatools

Any suggestions will be gladly received.
