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

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.

fusion drive a hard disk drive with a NAND flash storage. this has been around for nearly a decade and exists in MAC as a cost savings measure at the expense of performance and is best suited toward mac customers as the moniker is far more critical to them than any demonstrable value.

Re: Uhm, That's kinda why it is called a BETA...

[that this is not und]

It is nice when nasty things don't happen to you that require a vendor to fall back to disclaimers. It's not the norm for beta testers to get fucked over like this. Yes, Apple is covered from liability. Their shortcomings can fuck over their beta testers without Apple having any liability.

Are you satisfied, now that your assertion has been fully fleshed out?

You're welcome.
