64-bit MacBook Air M2 problems

[Ian West]

Dear Jean,
        I have been using Lilypond for some 10 years; first 2.12.3, then 2.18.2.
        I just bought a new MacBook Air, which uses the new 64-bit M2 chip. I 
understood I could not use the 2.18.2; that the 64-bit chip required the 
“unofficial” version 2.20.0. So I loaded that, and it runs all the tunes that I 
tried. But it is very difficult to write new music. It is proving very hard to 
work out what some of the problems are.
[1]. There is some new language to learn, new ways to do things. But the 
manuals v2.22.0, and  v2.22.2 help and I am learning.
[2]  There are some baffling problems. It seems that the single apostrophe 
(used to raise the pitch by one octave) on the keyboard does not work. But, if 
I copy-and-paste from the manual, I can get round that problem. 
[3]  The header section is absurdly sensitive. I can paste in from the manual:
\header {
  title = "SUITE I."
  composer = "J. S. Bach."
}
and it works. But my piece is by Monteverdi. I can change the title to “Take 
not my treasure”, but I cannot change Bach to Monteverdi. !!!

        Yours sincerely, Ian West
