Re: Lilypond on OS X Catalina

[Allan Kinnaird]

Thanks for that, Hans, but I don’t understand what it means.
I just want to be able to use Lilypond. Nobody who has bought a Mac since the 
launch of OS X 10.15 will be able to use Lilypond, and nobody else who uses 
Lilypond already can safely upgrade to the latest OS version.
