MacOS 11 is about to be released, so this is a LilyPond 2.21.80 installer, latest unstable release, for use on MacOS 10.15. As it will take some time to get MacPorts working on Mac OS 11, and this installer likely will not work on it, the best shot is to install this on MacOS 10.15 and then upgrade.
The installer is made from MacPorts lilypond-devel, available on the link below [1]. It installs in /opt/lilypond/, with the program in /opt/lilypond/bin/lilypond. If you have already something installed in this directory, it may be prudent to remove it first. This can be done by the command sudo rm -rf /opt/lilypond 1. https://web2.storegate.com/share/wiM8LyF It may be the case that 'lilypond' is best to be run from a script that sets LC_CTYPE=en_US.UTF-8 (which otherwise on MacOS is LC_CTYPE=UTF-8). It can be created and installed as follows: In Terminal write (^D is <control>D): % cat > lilypond export LC_CTYPE=en_US.UTF-8 export LANG=en_US.UTF-8 exec /opt/lilypond/bin/lilypond "$@“ ^D % chmod a+x lilypond % sudo -s cp lilypond /usr/local/bin/lilypond The program can then be called by 'lilypond' in Terminal, as /usr/local/bin/ is in the program searchpath. And do 'rm lilypond' if you do not want to keep the local copy of the script.
