I am using 2.3.7 on macOS Sonoma (and before that on Monterey) and I do not 
experience any slowdown. My document is over 1000 pages split into less than 10 
files. It certainly contains paragraphs which are much longer than a few 
sentences. So I presume that  it could be an issue with your configuration. 

In your preferences I noticed:

# LyX 2.0.4 generated this file. If you want to make your own
# modifications you should do them from inside LyX and save.

Format 1

Just a stab in the dark as I do not know anything about the inner workings of 
LyX, but could it have anything to do with that old version of LyX and the very 
old Format number?

LyX is painfully slow on my Windows computer, but this is a 5 year old Pentium 
Surface Go, which was severely underpowered even when it was brand new. Event 
on that machine I did not experience any dependence on the length of the 
paragraph.

Re: Problems with LyX on Mac computers

[Marcus Kriele via lyx-users]

Ed, have you tried LyX 2.3.7, which came out very recently?  I believe it is  
universal, if you take the correct installer (there are two to choose from, one 
for old versions of MacOS and one for the newer ones which support arm.

Re: About upgrading to MacOS 13

[Marcus Kriele via lyx-users]

Hi Daniel

Please note that Time Machine may not work for going back from macOS13 to 
macOS12. At least it did not work in my case.  I also realized that macOS13 
changed the format of the Photos library so that I could not read it with 
macOS12 after reinstalling the old operating system (fortunately I had a recent 
backup for this library). 

So if you try to upgrade I would strongly suggest to make a full backup first 
without using Time Machine to ensure that you still have all your data, if it 
does not work out.

With "absolute path" I mean the path from the root directory to the csv file, 
so the complete path to the file in the file system. 

But to be honest, I really think that If you are only interested in producing 
plots, LyX is not the best tool. LyX is fantastic software for producing 
written documents, and it is easy to include plots and pictures.  But it is not 
the best program to produce stand-alone plots. My advice would be to get a good 
editor with a nice LaTeX environment. “Emacs"  with the library “auctex" or 
"Visual Studio Code" with the plugin "LaTeX Workshop" are great free choices 
for Linux, Mac or Windows. If you never have worked directly with LaTeX before, 
you will find a minimal plotting example  in the first tutorial of the official 
documentation of TikZ and PGF (PGF manual) .

I assume you are using a raw latex inset in LyX.  Have you tried an absolute 
path?  If you produce a pdf, then LyX creates a temporary  LaTeX document in a 
directory for temporary files first and then processes this LaTeX document in 
order to create a pdf.  As far as I know (but I may be mistaken), raw LaTeX 
input is copied verbatim into this LaTeX File.  As the temporary directory is 
normally different from the directory of your LyX file, it would not find csv 
files with a relative path.  You can set the folder for your temporary files in 
the preferences, but this is a general setting and not a per document setting. 
So I would not recommend doing so for finding your csv file. 

I think, a better approach would be to produce a pdf for your plot outside LyX 
and then to read the pdf into LyX as a figure.  Advantages: the figure input 
dialog does accept relative paths, you can use an editor which is better suited 
to do LaTeX work (syntax highlighting etc), if you have a large document with 
many files the LyX compilation is much faster because it does not have to 
process TikZ (which is slow) every time.

Re: Re MacOS Ventura trouble

[Marcus Kriele via lyx-users]

I had  the last 12.x which came out before Ventura. So it was very likely 12..6 
and at least 12.5   But I did not install Python 3 on Ventura.  This was 
probably my mistake

Re MacOS Ventura trouble

[Marcus Kriele via lyx-users]

Thanks for both your answers

@JMarc: I simply upgraded to the newer Mac OS. Prior to the update, LyX was 
running smoothly, so  I would assume that I had Python 3.0 as well. An 
OS-update shouldn’t delete existing programs. In the meanwhile I have 
downgraded OS again and cannot verify anymore whether I did have Python 3.0

@el:  I I have an ARM MacBook Pro. So if you could post whether it worked for 
your M1 MacBook would be helpful to anyone who might have read about my 
troubles.
