MacOS High Sierra is coming, and with it APFS – but not for all of us, it seems [atualizado]

Apparently, we're less than two weeks away from Ma's next glorious (or not) keynote and, among the many new features that the company is likely to present there, one of them is certainly the final release date for the MacOS High Sierra. .

The new version of Apple's most complex operating system brings, among several improvements, one that may go unnoticed in the eyes of the unwary but certainly make a big difference in everyone's daily life: the new file system Apple File System or APFS, for the last.

We have already talked in detail about APFS and its benefits in this article; a detail that nobody knew so far, however, was discovered today by the people of the site 512 Pixels: Apparently not everyone will enjoy the benefits of the new system when High Sierra arrives at least not automatically.

As you well note from this Apple page that gives you the way to prepare for the transition, only fully flash storage systems (SSDs) will be automatically converted to the new file system; In this case, the transition is mandatory and completely invisible, without the need for user intervention. Machines with hybrid drives like Fusion Drive or just hard drives, however, will not be part of the joke, as Ma says:

Systems with hard disk drives (HDD) or Fusion drives will not be converted to APFS.

This is an ambiguous phrase: while on the one hand it is clear that these system types will not be automatically converted to the new file system, on the other hand there is no clue that you can make this transition later manually (see the update below). ).

As is well known, APFS is designed to take full advantage of the features of flash drives; Maybe that's why Apple didn't bother to convert old volumes to it, but it would be nice to see the company giving the most advanced users the opportunity to embark on the new technology. The existence of this option, however, can only be confirmed with the arrival of the High Sierra.

Other questions are clarified on the page; for example, Apple makes it clear that HFS + formatted volumes can be read / written by APFS devices; already volumes on APFS can only be read / written by devices either on APFS or alternatively on HFS + provided running macOS Sierra 10.12.6 or higher. For FileVault, HFS + encrypted volumes will be automatically converted to APFS, if applicable, without major problems.

Almost without exception I, for my part, have not seen a single one so far, users testing the High Sierra betas have reported that the transition from HFS + to APFS is being absolutely invisible and smooth (as with iOS in transition to version 10.3); ?ordinary? users, therefore, need not worry about that.

As confirmed by our reader Alan Rodrigues (thanks!), based on the High Sierra betas, yes, it is possible to manually convert to APFS if you have a Mac with HDD or Fusion Drive just access the diskutil tool in System Recovery mode.

Less bad! ?
