New Apple File System Coming in macOS High Sierra Won't Work With Fusion Drives

This should of been mentioned to the Developers testing betas....
I have been testing and installing all of the Betas without issue; up until this weekend when I had time to install the GM.
I was forced to open a bug report this weekend because of all the failed attempts to get the GM installed... thus forcing me to restore twice from Time Machine backups, to provide proof that there was something wrong either with the installer, or a Fusion Drive issue.
Glad to know that I will have to restructure my current Fusion Drive just to upgrade...

Don't look now but....Fusion-gate.
If the SSD is your boot drive, I'd expect it will be converted. The installer is going to be looking at the boot drive type - if it's a CoreStorage Volume (Fusion) or HDD, it won't be converted.
Wonder if they will flush out all spinners/fusion drives on Macs when they ship with High Sierra.
Sad, but totally Apple these days. Marketing screamed, "Release it" and the minions will, no matter whether its ready or not, management just sits back and counts its money.
totally! this is a good reminder to not jump on a Beta with your main computer.
Yes a new file system not working on drives they have sold very few of recently will surely be the death of Apple.
Glad I went 512GB all SSD for my 2017 5K iMac. All flash should be standard by now on all iMacs. It's been 5 years since the Fusion Drive was first released.
Disorganized roll outs without any clue how to market the products?
Kinda funny people would rather have a presumably still buggy beta feature shipped, and lose all their data.
This is a frigging beta feature. By definition it could be removed or postponed.

Anyone care to try to explain how Apple has the gall to pull this crap while continuing to sell Macs with fusion drives? Are any adults actually in charge of anything?
It still hasn't been released and no one has been harmed in anyway. If you consider a tester running beta 1 to be harmed because they have to re-install you really don't understand the process at all.
This whole time, I was thinking APFS was going to give my iMac w/ 3TB Fusion Drive more life. It already feels 1/4th the speed of my MacBook Pro equipped with an SSD especially when I reboot or launch a program like Lightroom.
The APFS advantages would have certainly been nice day to day but with a file-system migration, I'm glad Apple is perfecting it and I hope they don't ditch it entirely.
This is why I don't participate in the beta program anymore though. I think I stopped 2 years ago. Public Beta is nice but only possible on computers we don't use to get work done.
With this news, it's possible that I wait for the x.0.1 update just in case.

LOL. OK, fair cop. I deserve that. Gigs... I meant gigs. Megs of gigs!
What's with the complaints here?
The file system is one of the most few critical subsystems in an OS, you DO NOT want Apple to mess this up because your files can be irreversibly corrupted, including backups. Imagine your files in iCloud's Documents being corrupted, all of your Macs not running HS would have the same corrupted files. A lot of users do not back up their stuff, so Apple isn't going to risk it.
File Systems take several years to a decade to build and perfect, Apple has been working on this for slightly more than four years now.
You'll get APFS when it is ready for your spec.
By the way, all iOS 10.3 users have been been using APFS. Are you going to switch away from macOS because they got it first for several months?

I have an external boot APFS Thunderbolt 2 HDD. I've been doing a late beta and downloaded the Golden Master over the weekend. This is on an iMac that internally has a fusion drive. As of my last check with APFS specs, it SHOULD work fine on an internal HDD. It MAY even work on an internal HDD txt was "split" from its Fusion drive (didn't dare try the myself).
I believe that all macs with pure boot SSDs will be forced into the APFS conversion, whereas boot HDDs MAY will be offered the option to convert to APFS.
What I had to do with High Sierra beta 9 was format a partition on my external LaCie Thunderbolt 2 drive as APFS, and THEN install High Sierra. It's a long, slow process...

Well that's a bummer, but since I'm running off an external SSD, it doesn't impact me.
What gall? All options not being able to use all features of free OS upgrade does not seem to be particularly galling. You can still upgrade and use HPFS+.
But people keep buying, so why would they stop their practices ? If anything its pedal to the medal..all the way to a trillion.
FYI, the High Sierra Golden Master isn't out yet. This article got my hopes up .
The Golden Master Candidate is likely not the same build as the GM and is still labeled as beta. It's what other companies call a Release Candidate (RC) or silver build. With Yosemite there actually has been 3 GM candidates before releasing the GM.

I don't get it ... I installed the GM on my iMac with 1TB Fusion Drive. It installed just fine. And it seems to run at the same speed it always had. What's the issue here? I'm not in front of the computer ATM to see if it's APFS converted or not.
