Hi, I encountered the same problem here. Anaconda’s installer edits ~/.bash_profile (I suppose) or ~/.zshrc (for the most recent versions of macos) to prepend the PATH.
That means of course the correct PATH is only available within the terminal. A simple (not very macos like) solution is to run texmacs from the terminal : open /Applications/TeXmacs.app An ugly fix would be to add anaconda’s path on top of /etc/paths (I have no idea what that might break in the future though) Now I tried the (define (python-command…)), but it didn’t seem to work though… Pierre-Henri > Le 11 déc. 2020 à 19:03, Massimiliano Gubinelli <m.gubine...@gmail.com> a > écrit : > > Dear Joris, dear Darcy, > > one of my collaborators had problem on Mac with python.
