Apple File System in macOS High Sierra Won't Work With Fusion Drives (arstechnica.co.uk)

Posted by msmash on from the beware dept.

An anonymous reader shares a report: MacOS High Sierra will come out of beta and roll out to the public next week. If you have previously installed the beta version, you may need to take extra steps before installing the release so your Fusion Drive-toting machine doesn't experience any negative consequences. Apple announced that the new Apple File system (APFS) won't immediately support Fusion Drives and will only support systems with all-flash built-in storage in the initial release of High Sierra. Those who tested out the beta versions of macOS High Sierra had their Fusion Drives converted to the new APFS. However, support was removed from the most recent beta versions, and it isn't coming back with the public release of High Sierra. Apple provided a set of instructions to help those users convert their Fusion Drives back from APFS to the standard HFS+ format before installing the High Sierra update. The instructions include backing up data using Time Machine, creating a bootable installer, reformatting the machine using Disk Utility, and reinstalling the operating system update.

    Why is this even news? A feature in a beta version of software got cut for the GM. Happens all the time. Any idiot can read between the lines and understands that there's a bug in APFS for fusion drives, and rather than delay the release, Apple is just disabling it on fusion drives until a point update down the line.

    Nothing to see here. Move along.

      It is news because some people with Fusion Drives expected to be upgraded to the new release and the new filesystem, but now won't. They may be developers, integrators, or whatever, and this lets them know that APFS is delayed for their kit until later.

      Apple's new operating system does not support a feature that they currently sell at a premium because they don't offer large flash drives. That's a significant failure on their part and affects many people who should read this article as advice not to upgrade.

      That's news.
