Error Could Not Create A Preboot Volume For Apfs Install High Sierratheres

APFS offers a lot of advantages for SSD performance and durability, as well as encryption for any type of drive.

But its not backwards compatible with older versions of OS X or macOS.

Error Could Not Create A Preboot Volume For Apfs Install High Sierratheres

Youre required to upgrade any SSD startup volume when you install High Sierratheres no way to prevent it.

There was a choice to bypass migrating to APFS while installing High Sierra during the beta period.

However, Apple removed that checkbox for the final release.

An earlier version of this article misstated that the checkbox remained.

My apologies.) This shouldnt be a problem, because its unnoticeable, but it might be a reason for you to delay moving to High Sierra if you have an SSD boot partition and want to make sure no APFS issues emerge for other people.

Its rarely a bad idea to wait for macOS 10.X.1 or even 10.X.2.

Apple hasnt said exactly when a Fusion APFS upgrade will be ready.

However, we expect that because theres no upgrade choice for APFS with High Sierra, the Fusion upgrade will also be mandatory when it ships.

How to upgrade to APFS in Disk Utility If you want to upgrade an external SSD to APFS, you can do so via Disk Utility.

However, Id recommend holding off converting even qualified external drives that you dont use for booting a Mac, as you wont see enough of an advantage, while losing backwards compatibility with macOS prior to Sierra, which is the only previous release that can read and write to APFS volumes.

Note: An earlier version of this article relied on a feature only available in late beta to choose whether to upgrade an SSD boot volume to APFS.
