No he hecho una copia de seguridad de mis archivos, pero he leído que este proceso no debería borrar ningún dato del disco original. ¿Hay algo que pueda arreglar esto?

Actualización

He conseguido arrancar en MacOS, pero el último paso no me funcionaba. También faltaban los 32 GB. Aquí está la salida de diskutil list y gpt -r show /dev/disk0 .

Usted casi lo hizo bien. Después de usar gpt create deberías haber vuelto a gpt add . Pruebe la siguiente secuencia.

Nota: He omitido cualquier diskutil unmountdisk /dev/disk0 comandos que puede necesitar introducir.

dd if=/dev/zero of=/dev/disk0 bs=512 count=1 
gpt destroy /dev/disk0
gpt create -f /dev/disk0
gpt add -b 40 -s 409600 -t C12A7328-F81F-11D2-BA4B-00A0C93EC93B /dev/disk0
gpt add -b 409640 -s 427293056 -t 7C3457EF-0000-11AA-AA11-00306543ECAC /dev/disk0

Si tiene éxito, puede introducir el comando que se indica a continuación para volver a añadir el espacio libre a MacOS. (Es posible que tenga que reiniciar a MacOS antes de introducir el comando).

sudo diskutil apfs resizeContainer disk0s2 0
