Dear Francesco: > Any clues on what I should do to make Frescobaldi/LilyPond work ?
I have been using Sonoma on M2 (and I will *not* upgrade my OS…), but if Tahoe 26.2 is anything like recent MacOS on Apple Silicon, I might venture to guess that it has something to do with file permissions and, especially if you manually installed the LilyPond yourself, you might need to actually manually tell MacOS that LilyPond is a legitimate thing and they should recognize in your system. You might try the following: 1. start up a Terminal application (/Applications/Utilities/Terminal.app) 2. type in: "sudo xattr -rd com.apple.quarantine " NB: without the quotation marks at the beginning and the end (and note the space at the end; that space must be there) 3. Drag/Drop the LilyPond folder you placed from the Finder into the Terminal window with the "sudo ..." command typed in. The result should be a line in the Terminal window that looks something like this ( sudo xattr -rd com.apple.quarantine /Users/francescointrieri/(etc. etc. etc…) 4. Hit <return>, enter your password, hit <return> again. I hope that works for you! Best wishes, Yoshi -- -- -- Yoshiaki Onishi https://github.com/yoshiakionishi/lilypond-snippets
