Hace unos tres años sustituí el disco duro original de mi MacBook Pro de 2010 por una unidad SSD para que el sistema funcionara más rápido. Funcionó bien hasta ahora.
Lamentablemente me encuentro en esta situación ya que mi sistema seguía arrancando y cuando se encendía finalmente siempre empezaba con una ventana emergente que decía que había que enviar un informe a Apple. Sucedió varias veces y finalmente dejó de arrancar por completo.
Saqué el disco duro SSD y empecé a investigar y a buscar respuestas en foros online. Lamentablemente, en mi caso la unidad de partición es/era mi unidad principal de MacOS y tiene muchas fotos y datos de la familia. Por desgracia, no tengo ninguna copia de seguridad de todas las fotos y datos de la familia desde que lo sustituí por el disco original.
Mi unidad de partición principal SSD se muestra como 'FFFFFFFF-FFFF-FFFF-FFFFFF'. He puesto el viejo disco duro original de nuevo y arrancó mi macbook de ella y conectado SSD a través de USB y la partición principal ahora se muestra como 'FFFFFFFF-FFFF-FFFFFF-FFFFFF'.
Como he estado buscando una solución sobre cómo arreglar y venir a través de un número de puestos y he leído los puestos de solución de Klanomath resolver este problema.
Cuando se aconseja ejecutar el comando add gpt suele haber una cadena larga después en sus soluciones, por ejemplo
sudo gpt add -i 2 -b 409640 -s 820115416 -t 7C3457EF-0000-11AA-AA11-0033…
¿Cómo se determina eso?
He publicado algunas fotos a continuación. Puede aconsejarme la cadena de comandos exacta que debo ejecutar?

así que la partición ya no aparece como ffffff-ffff-ffff pero todavía no puedo ver el contenido ya que creo que necesito Sierra o una versión superior. Ahora voy a reemplazar la unidad original con este SSD y espero que va a arrancar. dedos cruzados. Voy a informar de nuevo. captura de pantalla a continuación desde Disk Utililty
Por desgracia, el SSD no arrancó. Intenté instalar High Sierra en el disco viejo que tiene Yosemite pero tampoco funcionó. Por lo tanto, he pedido un nuevo SSD que usaré primero para instalar High Sierra y así poder acceder a los archivos del viejo SSD. Después de eso tengo la intención de utilizarlo como una copia de seguridad de Time Machine para el futuro. Informaré de los progresos realizados.
