Hi Bruce,
If you want to use your standalone version of ConTeXt, you should create a specific « .engine » file for this and then in TeXShop use that engine. Here is what I have when I typeset a file in TeXShop using mkiv ConTeXt:
%%%%% begin file mkiv.engine
#!/bin/bash
export PATH=/Volumes/OK/context-minimal/tex/texmf-osx-64/bin:$PATH
context --synctex=zipped --autogenerate "$1" --purgeall
%%%%% end file mkiv.engine
you should replace the line « export PATH=…. » by the path to your installation of ConTeXt.
Best regards: OK
PS: regarding the installation and updates of ConTeXt on Mac, Thomas Floren has written a nice Apple Script which you can find here:

I can now run the example on the First Document web page, running ConTeXt from the command line. That works perfectly.
When I try to run the same file from within TeXShop, however, it tells me:
! Undefined control sequence. l.2 \startsection [title={Testing ConTeXt}] ?
I have created the file "ConTeXt Suite.engine" in directory ~/Library/TeXShop/Engines, per the instructions on the Mac Installation web page.
So I am not sure why TeXShop does not know about \startsection. I would be grateful for your advice on this.
Sincerely, Bruce
