Hi Alan, I have an almost identical set-up (M1, MacOS12.6, TexShop, useAlternatePath, useConTeXtSyncParser). One important difference, I use sync method: SyncTeX (TeX ≥ 2010) I’d recommend trying that. There are some other differences in my setup that probably are not important. At the beginning of my files (products and components)I only use the two lines % !TEX useAlternatePath % !TEX useConTeXtSyncParser not the root and TS-program lines, but I don’t think that matters for your SynchTeX issue. Here is the engine I use for LMTX, just in case it has something helpful for you. #!/bin/zsh # # This engine uses TeXShop's "Alternate Path", which is the variable "$3" below. # Set the TeXShop's alternate path to your ConTeXt installation in # TeXShop's Preferences -> Engine -> Alternate Path # Start ConTeXt source files with the lines: # % !TEX useAlternatePath # % !TEX useConTeXtSyncParser export OSFONTDIR=/Library/Fonts/:/System/Library/Fonts:$HOME/Library/Fonts export PATH="$3":$PATH mtxrun --autogenerate --script context --synctex "$1” I put that long comment in the engine because I share it with collaborators. Hope that helps! Gavin

At the top of a single source file, I have the lines: % !TEX root = prd_Aestimatio-0301.tex % the root file % !TEX TS-program = ConTeXt2021 % !TEX useAlternatePath % !TEX useConTeXtSyncParser \setupsynctex[state=start, method=max]

Syncing works well enough—though I can see no difference between method =min and method=max, both highlight only a few words and not the entire text to be synced, but perhaps my expectations are out of line.

When I have these lines at the top of a component file and typeset the product file, I get a rootfile.synctex file, but syncing itself goes awry. Nothing happens when I sync from the PDf file to the component file, and when I sync from the component file to the product PDF, I get the correct page but no highlighting.

I am using TeXShop ver. 5.03— sync method: Both Pdf Sync and Search Alternative Path: /Users/bowen1/Applications/LuaMetaTeX/tex/texmf-osx-arm64/bin

and also the latest ConteXt (ver. 2022.10.15 10:37 LMTX) under macOS 12.6 (Apple M1 Pro chip)

Note: the product file has only one component file for now.

I suspect that I am missing something but am not sure where to look or what to do now. Any guidance will be much appreciated.

Alan
