I remember having this problem in the past, but I don't think it was resolved. It could be related to them using an M1 Mac/newer MacOS version, but not sure if that is the reason.

I instead sent the user our fork of PONscripter to try out, which at least boots up and runs fine (for now).

I'll wait a little while to see if there are any issues, but I think we should replace all the MacOS exes with our fork of PONscripter (or maybe just the voice only versions?),

The same forked Ponscripter executable can be used for both the voice-only and full mod, due to the extra features Tellow put in for our mod.

TODO:

- [ ] Update wiki manual installation links (for both voice-only and normal mods) to use our forked MacOS exe
- [ ] Update installer to use those same executables
- [ ] Fix "MacOSX Only: you might need to rename the 0.u file to 0.utf" message on this page https://07th-mod.com/wiki/Umineko/Umineko-Part-1.1---Voices-only-Patch/ , if the new exe is used.

El issue trata sobre actualizar la wiki y el instalador para usar un ejecutable de PONscripter bifurcado para macOS. Comience localizando las páginas de la wiki mencionadas, como los enlaces de instalación manual y la página específica con el mensaje de cambio de nombre. Revise el repositorio en busca de scripts de instalación o archivos de configuración que hagan referencia a los ejecutables antiguos. Reemplace los enlaces a los ejecutables antiguos con la nueva versión bifurcada y actualice la instrucción de cambio de nombre si el nuevo ejecutivo ya no la requiere. Verifique los cambios revisando la estructura de la wiki y cualquier script de instalación asociado.
