Re: Problem

[Jacques Menu]

An Mac .app bundle is self-contained, with everything it needs inside it. 
That’s why you can place anywhere in your files hierarchy and there can’t be 
conflicts with other applications, including other versions of the same .app. 

In particular, the LilyPond .app bundle contains the python version to be used 
with it:
jacquesmenu@macmini: ~ > ls -sal 
/Applications/LilyPondWithLilyjazzFont.app/Contents/MacOS
total 248
  0 drwxr-xr-x@  4 jacquesmenu  admin    128 Feb 12  2017 .
  0 drwxr-xr-x@ 18 jacquesmenu  admin    576 Jun 27  2017 ..
184 -rwxr-xr-x@  1 jacquesmenu  admin  92080 Feb 12  2017 LilyPond
 64 -rwxr-xr-x@  1 jacquesmenu  admin  29564 Feb 12  2017 python

I didn’t know, though, that moving it other that with the Finder (in the 
terminal with mv, for example) would raise issues in the recent, 64 bit only OS 
versions.

The LilyPond executable inside it can be launched thru its access path and used 
in Frescobaldi… provided it can run on the given architecture:

jacquesmenu@macmini: ~ > 
/Applications/LilyPondWithLilyjazzFont.app/Contents/MacOS/LilyPond 
-bash: /Applications/LilyPondWithLilyjazzFont.app/Contents/MacOS/LilyPond: Bad 
CPU type in executable

I currently use this version, which is not part of any .app bundle:

jacquesmenu@macmini: ~ > type lilypond
lilypond is /opt/local/bin/lilypond

jacquesmenu@macmini: ~ > lilypond --version
GNU LilyPond 2.22.1
