On the Mac (deduced from the icloud address) find /Applications/LyX.app/ -name lyx2lyx -type f
tells us /Applications/LyX.app/Contents/Resources/lyx2lyx/lyx2lyx Try the complete path/file name on the old file and see what that says. Looks a little like a TeX installation issue, just to be sure, you did install TeX, right? I use Homebrew, which has three versions ((annually) updated) brew install mactex brew install mactex-no-gui brew install basictex I use the latter, and apply a small modification to the default TEXDIR=$(dirname $(kpsewhich texmf.cnf)) TEXPARENT=$(dirname $(dirname $(kpsewhich texmf.cnf))) perl -i -p -e 's+\$SELFAUTOPARENT/+/$TEXPARENT/+' $TEXDIR/texmf.cnf As I have multiple systems I can update the packages missing after an update of basictex easily with something like tlmgr install $(ssh -C USER@HOST tlmgr list --only-installed \ | awk '{gsub(":","",$2);print $2}' and so don't need to have the complete installation. I also like long error lines and do so something like this brew install gsed for i in error_line max_print_line half_error_line do gsed -i "/$i/d" $TEXDIR/texmf.cnf done cat >> $TEXDIR/texmf.cnf <<EOF error_line=254 half_error_line=238 max_print_line=1000000 EOF The EOF must be at the beginning of the line On 12/10/2022 00:04, ahostmadsen--- via lyx-users wrote: > Thanks, you mean running lyx2lyx from the terminal?
