Solved! Thanks so much Stephan! This was it.
I installed Python by way of... xcode-select --install and I now have Python 3.9.6 I'm sorry I didn't notice the previously reported Ventura issue, as I only ran into this problem when I was trying to convert a file. Newer files were loading. So I didn't search for Ventura issues in the forum. LyX rocks and this mail list rocks. Thanks again Stephan. -Iván On Sun, Dec 4, 2022 at 6:10 PM Stephan Witt <[email protected]> wrote: > Am 04.12.2022 um 23:56 schrieb Ivan Werning <[email protected]>: > > > > Hi > > > > Help!
