Installation SSD sur MBP 13" mid 2012

[kormo]

Bonjour,

Ma fille a récupéré un Macbook pro 13" de 2012 (le 9,02) qui fonctionne encore (très lentement) sur Yosemite.
Je souhaite le rafraîchir avec un SSD Crucial BX500 et 16go de RAM, avec un mac os plus récent et surtout clean !

J'ai une clef usb avec l'install de MacOs HighSierra et je me demandais si, une fois le SSD installé et formaté comme il faut, je pouvais booter dessus, et dans la foulée, installer HigSierra ?

Merci de vos avis éclairés

Ahhh oui j'vais oublié celui-là !
Mais y a pas aussi une question de SIP ?



Sinon, voilà le résultat :
