I haven't tried LMTX yet, but you may configure the path to the ConTeXt
executable you want to use by setting `g:context_mtxrun`, e.g.:

    :let g:context_mtxrun='/path/to/context/mtxrun'

Then, executing :ConTeXt will run the configured command. You may also
define shell enviroment variables, if needed. For instance, I have
configured Vim to use my installation of ConTeXt Beta as follows:

   :let g:context_mtxrun='PATH=$HOME/path/to/context-beta/tex/texmf-osx-64/bin:$PATH mtxrun'

You may show a log of Vim messages by typing :messages.
If you post the error message, I may better diagnose your issue.

That's unnecessary. MacVim's runtime path is searched by default.
I recommend that you remove the files that you have copied into ~/.vim.
ConTeXt in Vim works out of the box.
