The TeXshop engine file says:

# Before using this engine, you must run the following command once in Terminal: luatools --generate

I probably did this when I installed TeXLive.

But I’m a little irritated by /sw/bin/.
Is this a real MacTeX installation and not something like homebrew?

Let’s start with the simple things:

What is the result of:
which context

it should be:

If that doesn’t work try:

which pdflatex

The result is probably not


but should give some indication where to look.

There may be an old installation of MacTeX without Context somewhere in the path.

If this is an old TeXShop installation, the Context engine may need an update because it points to the old PATH.
Simply copy the engine from ~/Library/TeXShop/Engines/inactive/ConTeXt to ~/Library/TeXShop/Engines

Hope this helps
