All indications are that Mojave will not boot at all unless the disk is APFS, so if you want to use Mojave, you'll be using APFS.Hi guys, please enlighten me on this one, is it worth it to upgrade my Fusion Drive (1TB - iMac 5k late 2015) when Mohave comes out? Would be great if there are benchmarks on the same system
Hmm, thank you for the info.All indications are that Mojave will not boot at all unless the disk is APFS, so if you want to use Mojave, you'll be using APFS.
During my day to day usage, I don't see any performance hits with APFS but boot up (since HS) is painfully slowMore data reliability, but slightly slower, is the likely outcome. Choose your pick.
To start, it's not possible to run the Mojave installer and not convert to APFS. Even when doing a clean install using the command line options, the old method of installing using "--converttoapfs NO" does not work anymore. I have not personally tested but have seen reports that an APFS installation cloned to an HFS+ drive will not boot either.chrfr wrote:

Have you tried this yet, yourself?
What "indications" can you document?
I used SuperDuper.What app did you USE to create the clone?
CarbonCopyCloner? SuperDuper? Something else?
I'd like to try it to replicate your discovery.
Yours is the first post I've seen of someone booting and running Mojave under HFS+...

Well, there you go.
You have just proven that it IS possible to boot and run Mojave under HFS.
Even though you added:
"there's still no way to install without converting so it won't surprise me if Apple gets rid of this functionality before release"
... That's not "the point".
Of course Apple may not want the average user to install Mojave "as HFS+", and not provide any "direct way" to do so.
But... that doesn't mean it can't be done.
Again, you have just proven that it CAN be done, with your exercise above.
Question:
What app did you USE to create the clone?

Because "some of us" prefer HFS+ and have no interest in APFS (at least at this time, until it becomes more proven).
Let me give you another example of Apple trying to "control" what a user does:
It's in Mail.app.
When one sets up a new account, Apple makes it all-but impossible for the average user to choose a POP style setup. The app "pushes" one towards IMAP and offers no easily-seen option for POP.
It'a still possible to use POP, but one has to literally "trick" Mail.app into presenting the appropriate setup screen.
I'm a POP user and have no interest in IMAP. I will keep using POP so long as POP is able to be used.
That's just the way I want my email to operate. Nothing more to it, really. My computer, my choice.
So, to paraphrase your original statement... "it's quite obvious Apple does not want us to use POP".
BUT... it can still be used.
Told you that to tell you this:
If Apple doesn't want Mojave to run under HFS+, I believe they would make it impossible to do so.
It -is not- impossible, as chrfr demonstrated in his post above.
Apple may not WANT us to use HFS+.
BUT... it can still be used, at least at this time.
I intend to keep using it.

I had AFPS on my external SSD and the performance hit of that file system especially on boot up was significant. I'd be happy with 5 seconds. As it stands, I had to rebuild and reload macOS on my iMac and I opted to run off the internal drive and not deal with AFPS. I'm currently on High Sierra because of the issues with Mojave but I rather not go on AFPS when Mojave gets released.It takes about 5 seconds longer to boot up
WOW **** YOU APPLE.All indications are that Mojave will not boot at all unless the disk is APFS, so if you want to use Mojave, you'll be using APFS.
Agree with Stefdar and vince22 above.
There will be no APFS in this residence, ever.
(Or, at least until it becomes totally impossible to install and run HFS+ !!)
