    After my recent troubles with my mac and after help from an apple tech, my fusion drives became separated and I did a few commands in terminal to fix this, can you look at the picture below to see if my HD set up looks right?

    Anyone ? I get the feeling there's still a problem as my Mac still isn't running as fast as it did before moving to Mojave

    It looks good to me. But I don't consider myself fluent "in APFS".

    Looks fine to me! One fusion drive, one APFS container disk.

    Also, CMD + Shift + 4 lets you take screenshots of individual windows, so you don't have to snap a pic of your screen with your phone. It always ends up looking funny :)

    I'm really surprised that, with Mojave, APFS is now supported on fusion and HHDs after the problems during the High Sierra and Mojave beta.

    On a boot SSD, APFS is great and has a few amazing properties that, so far, do not extend to other volumes.

    Thanks for all the help guys. On a side note how could I run an SSD ?

    The least invasive method would be to use an external Thunderbolt or Firewire drive; there appear to already be multiple threads on that topic in this forum. (I'm toying with the idea of going that route myself with my 2012 iMac, which has an internal HDD.) The other option is to perform the proverbial heart transplant... that is, swap out your existing internal drive for an SSD. This method also leaves open the option to retain your previous config in its entirety, by moving the old drive into an external enclosure. (I actually did that with a 2006 iMac, many years ago.)

    But frankly, I'm not sure I'd actually recommend either of these options for you, since you already have a Fusion drive. I think you'd probably be much better off going back to that Apple tech to verify that your Fusion drive is working properly, because if the slowdown you're experiencing turns out to be unrelated to the hard drive, you might be setting yourself up for a very expensive disappointment, by just tossing money at an SSD. On the other hand, the tech should also be able to tell you if your drive is actually in the process of failing... so they could potentially help you avert a very frustrating data loss event. (Hopefully you have a Time Machine backup, just in case.)

    To put it another way: Unless you're already planning to entirely discontinue use of your Fusion drive for some reason, (such as age, as the most obvious example) buying an SSD is likely to only disguise the problem, while giving you very little back in terms of performance benefits. So, maybe try to find out for sure what's going on with that Fusion drive, first.

    Really? You know this how?

    The spinner is 6 years old. The chances of it being the source of the problem is around 100%. I am speaking from experience.

    Your opinion that replacing it will not give a major performance boost to a 2012 is wrong. I have fixed too many of these.

    The 2012 Mac is unique among those with fusion drives. The blade is SATA III and not NVMe PCIe like the 2013-on. This means that there is no performance benefit to replacing the hard drive only with an SSD. Neither is there a performance hit by tying together the two into a fusion drive from Mojave on. This is not true in High Sierra where APFS on fusion drives was possible only in Beta.
