Sierra Could Not Create A Preboot Volume For Apfs Full Installer Right

So, since you dont get the full installer right away, I decided to simply install High Sierra Beta over 10.11.

This worked, so I tried to do a recovery boot, reformat the HD to APFS and then install High Sierra Beta.

Looking around I found a way to create a bootable High Sierra Beta installation image.

Following these steps I created a external bootable High Sierra Beta installation image of Beta 5.

ENOENT: Query the kCFGetAddrInfoFailureKey to get the value returned from getaddrinfo; lookup in netdb.h.

Error code is the status code returned by the server OSStatus type from Carbon APIs; interpret using.

However, it has been shown in recent times that in the vast majority of cases if you simply run a clean install, then duplicate your old home folder to your new disk, you will get all of the same advantages as a clean install followed by manual migration, with a small fraction of the effort.

Two options are to use Duplicate (a free utility which can copy and paste an entire bootable volume), or Mac Backup Guru (a paid, fully featured backup utility with unique incremental backups capability) for that.

Go to the backup disk and use Duplicate (free) or Mac Backup Guru to right-click and select Copy on the home folder (eg: External BackupUsersBob ) and then Paste on the Macintosh HDUsers folder on the startup disk.

This migrates all of your personal data and settings to your new home folder.

Then migrate the applications by selecting Copy on the External BackupApplications folder on the backup disk then Paste on the startup disk (eg: Macintosh HD ).

This will copy all of the applications which are present on the backup disk but not present on the startup disk to your new Applications folder, and automatically skip any applications which are already on the startup disk.
