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

[DesterWallaboo]

So they discovered issues with non-SSD drives during the beta process. Isn't that the entire point of doing beta testing? Apparently the bugs were large enough they have opted to push back support for the new file system non-SSD machines. No big deal. Imagine the kludge that would happen if they released support for non-SSD drives and it ended up being a total nightmare?

Sucks man. To be fair, SSDs were a lot more expensive option in 2014. Your machine is out of warranty now (or nearly), so you could probably crack it open and swap out the HDD. I haven't looked at guides in recent years but know it was possible in the past. OWC usually has drives and iFixit usually has guides. Though eventually they'll update it to support Fusion Drives. My old 2012 iMac at work (sitting next to my new one) has a fusion drive. I'll probably just use it as an external monitor once I get a thunderbolt cable.

The reason i actually got the Fusion was that B&H had a sale on a base model 5k iMac a few weeks after they debuted back in 2014. So with the no sales tax and the sale i was saving around $600 over the 256 GB SSD model. It was just too cheap to pass up

People running betas should expect to wipe their device at some point. Sometimes you get lucky and may not need to. That does not change what your expectations should be.

Clearly you missed the points. There have been so many missteps on this conversion to APFS. Apple is a company awash in cash with no mission anymore hence we get so much copying and less innovation but the press is compliant enough to not call them out on it.

This Filesystem change should have occurred years ago like Linux with XFS. Now it won't even occur for most of the macOS devices out there.

Its a big deal as APFS was supposed to debut at the beginning of this year! (they announced it June 2016) iMacs are the biggest segment of Apple computers and now it won't be on most of them. Seems like they should have caught this well before the 1st Beta.

I have run into the issue that system drives won’t convert. Just like Apple states in its notes.

Not me. I've converted several fusion systems without problem. Haven't tried it on my work laptop (since I can't be running a beta) nor any of my hackintosh all flash systems.

The article is aimed at Fusion drives. If you have a Fusion drive no matter what machine you run it on it wont work.

I will work fine, it will continue using it's current file system after you upgrade to High Sierra. Down the line Apple will fix whatever issue delayed APFS on Fusion drives and release an update to convert fusion drives to APFS.

I don't call issues with the file system a "small feature". More to the point, what other problems did they NOT spot with the filesystem none of you know about? A year from now you find your older files are corrupt? Yeah, it's not a bad idea to not adopt a new file system immediately regardless unless you enjoy being a guinea pig. As for the rest, I've had full Metal support for my Mini for UI since El Capitan and KODI has had HEVC support for years. You're talking about APPS. Try a spacebar preview with an iTunes movie and see how well "integrated" it is with the OS (hint: it won't let you view it unless you use iTunes or better yet have removed their encryption already, the latter of which will let you finally move AWAY from iTunes to something better like KODI, which runs on dozens of devices instead of one overpriced AppleTV (that has no support so far for Dolby Atmos or DTS:X or DTS of any kind, really, even though M4V files can hold DTS on them and KODI will read them just fine).

Apple TV plays my movies streaming from Plex just fine. I don't see any issues.

Plex is an App. I was referring to Apple's own playback software.

So happy I went through the pain-staking trouble of upgrading my 2011 27" iMac to a pure 480GB SSD. This will put my old iMac even further ahead.

APFS not working on even Fusion drives mean going forward, the single most important priority is getting the pure-SSD BTO should I ever upgrade from my 2011 iMac.

I think it's time Apple make a 256GB SSD stock iMac.

I’m trying to wade through all these comments, but I haven’t seen anything that at least people like us have to deal with: all-SSD RAID0 as a boot volume. My 2011 27” iMac has that. Will APFS support that?

UPDATE: I enrolled my iMac in the beta program today (the day before 10.13 is being released) and the installer will NOT install on the dual-SSD AppleRAID0. So I have to wait.

Plex does in fact use Apples own playback software, not its own.

Assuming APFS will support any Apple or third-party SSD drive though? Guess prices are coming down enough to do an older MacBook Pro upgrade to an SSD prior to updating to 10.13.

APFS is working fine on 3rd party SSDs.

It's still an additional app and using Apple's playback libraries is a massive LIMITATION not a positive feature for Plex. It cannot play DTS, DTS:X or Dolby Atmos enabled titles PERIOD with Apple's libraries. At best it can decode to PCM (no Atmos; no X). In its price range, you can get so much better hardware without those limitations. The only real reason to go with AppleTV is if you have a big investment in iTunes movies and therefore need it to play the encrypted files plus you get the 4K versions for free. Otherwise, until they relax what you can install yourself (e.g. KODI), it's rather pointless.

I’ve scoured the internet and couldn’t find anything— is it safe to install high sierra with a fusion drive? I had to revert back to Sierra using the lengthy process listed in the article. Are we good now that it’s out of beta?

Not much of a test, but I installed HS on my late 2015 iMac around noon today. It has a fusion drive, and the system report indicates it is (still) using HFS+. I'm only doing ordinary office work type tasks, but so far it has not shown any problems at all.

It's fine; you'll just still be using the old HFS+ filesystem.

I wondering when the the fusion drives will be supported on High Sierra??

Apple hasn't announced when.
