Glad my feedback seems to be useful.
[cutting a bit here]
Thanks, this makes sense. I should be able to set the variables correctly (and actually, the lilypond "binary" in the app bundle is already a script that sets a few variables and calls the real executable, so putting a few more in there should not be a problem).
Great. Glad it seems solvable.
Yeah, if it's just a question of setting a few variables, it shouldn't be too hard to fix.
#2:
Update.ly doesn’t work for me when invoked from Frescobaldi.
You mean convert-ly?
Yes. My mistake.
I get this message about a bad CPU type when I run it from Frescobaldi.
Weird, I haven't seen that. I'll try to reproduce. What version of Mac OS are you running?
I’m running 10.15.3 on a 2016 13” Touch Bar MacBook Pro. I’m using Frescobaldi 2.20.0. I seem to recall there are problems with the more recent versions on the Mac.
Hmm, I can't reproduce this on Mojave on my 2018 MacBook Pro (with the same version of Fresco, FWIW). Do you get this message with every file? Do you have a sample LilyPond file that you can share with me?
