Ok.
J'ai eu un soucis suite à un backup après avoir patché mon OS avec Open Core Legacy pour pouvoir continuer à bénéficier des mises à jour sur mon I-Mac version 15,1.
Voici les réponses dont la deuxième à résolu mon problème :
Apple's replicator (which must be used to copy the OS) won't work if the source snapshot is unsealed, and your patch has caused that to occur.
You have two choices:
- Back out enough of the patch to allow the snapshot to seal. You can then make a full copy, including the OS. Note that since your system is patched, this doesn't make much sense, because the backup won't be patched, and thus won't boot anyway (until it's patched)
- Use "Backup - all files" with "Smart Update" to copy everything BUT the OS (including all applications, settings and data). This can be easily restored by installing the OS to the drive (which in your case would involve patching it), then selecting the backup when prompted to restore during first boot
