Interestingly on my system the python3 is detected only if I install the Python 
package from python.org. The python3 in /usr/bin is not tried? Sorry, I didn’t 
read the code yet.

Yes, at first this is the best option probably.

My question for the future is how to act on next move of Apple. Neither I know 
when it will happen nor I know what happens. They announced to remove the 
preinstalled python altogether. ATM they provide python3 as wrapper. It’s 
asking the user to download and install the Command Line Developer Tools from 
Apple instead of doing anything useful. The exit status is 1. 

Currently LyX is using python (python2) and the warning info pops up once: „LyX 
needs to be updated“. Obviously this is wrong now. Python3 needs to be 
installed instead.

So I’ll have to investigate further.
