I have none of these problems but then I have been using LyX on a daily basis since 1998 (v0.12) (on Linux at first but since 2005 on the Mac in a busy Obstetrics and Gynecology practice)
And, I have installed 4 systems recently which all work out of the box... Here is what I have tested today: MacOs 10.15.3 LyX 2.3.4.2 I don't install TeXLive 2019, not even MacTeX-2019, but BasicTeX straight off of http://www.tug.org/mactex/morepackages.html At update time I run tlmgr list --only-installed \ | gawk '{gsub(/:/, ""); print $2}' \ > ~/Downloads/texlive.$(date +%Y-%m-%d).installed.txt from the command line (which requires the GNU awk (homebrew) but you can of course sed this) before the update and when done tlmgr install $(cat ~/Downloads/texlive.$(date +%Y-%m-%d).installed.txt) to make my additions survive. After installation of LyX, I (re-)run Tool->Reconfigure which is probably unnecessary. I change the default PDF format in Document->Settings->Formats->Output Format->Default Output Format to PDF (LuaTeX) which results in a change in the document to something like \default_output_format pdf5 and of course perl -i -p -e 's/(\\default_output_format)\W*(\w*)\W*$/$1 pdf5\n/g' *.lyx or even find ~/ -name '*.lyx' \ -exec perl -i -p -e 's/(\\default_output_format)\W*\w*\W*$/$1 pdf5\n/g' \ ';' will do that for all files As I like to use Skim for all PDFs on the Mac I just open one with Command-I and select Open With Skim Change All... and have to do nothing within LyX. If you like to use Preview for some and Skim for LyX PDFs, select LyX-> Preferences -> File Handling -> ~File Formats -> Viewer -> Custom and add something like open -a skim $$i As far as SyncTeX is concerned https://wiki.lyx.org/LyX/SyncTeX is helpful, look for "displayline' which in my LyX is one of the pull down options anyway. I change in Document->Settings->Formats->Synchronize with output the pulldown to \synctex=-1 which should be the default (but doesn't seem to be), save the LyX file, preview (CMD-R) and it works. In Skim in Preferences->Sync->PDF-TeX Sync support:->Preset I choose LyX and Shift-Command-Mouseclick works in reverse. Just a small note at the end, if you are looking for an "experience", buy commercial software. This is Open Source being maintained by very helpful, responsive and competent volunteer developers (in their spare time). If you find that the Wiki is incorrect, feel free to contribute by submitting changes or even amending accordingly. Personally I find posts under initials (anonymous) only, extremely annoying, especially when asking for help, even if an anonymous email address is being used for de-spamming purposes, which is quite in order. (That said, I hope that Thunderbird does indeed display my name in the From line :-)-O) greetings, el On 12/02/2020 17:22, mn wrote: > LyX 2.3.4.2, macOS 12 > > This is just a new user to LyX perspective: bad. > > Newly setup system: > > 1. install macOS > 2. install TeXlive2019 > 3. install LyX 2.3.4.2 > 4. install Skim > 5. read some docs for configuration > > (as written previously: trying to read UserGuide.pdf will not work in > this setup…) > > - Changing default PDF output in > > Preferences > Output > General > > to 'Skim' results in pdflatex output being displayed in X11/xpdf > > (As > Preferences > File Handling > File Formats > Viewers (PDF(pdflatex)) > is indeed set per default to 'xpdf') > > - trying to enable synctex support as per wiki is impossible > > — **none** of the options under > > Preferences > File Handling > Converters > > enables any 'OK' or 'Apply' buttons.
