Split Fusion Drive issue
I have a 21,5 inch 4K iMac with 1TB Fusion Drive but since I reinstalled (and messed about with the partitioning) my iMac takes 4 minutes to boot and once inside everything is slower than a tortoise and no fun to play with.
I've been looking for solutions for weeks and have now stumbled on a support article called How to Fix a Split Fusion Drive where it states "If your Fusion Drive appears as two drives instead of one in the Finder, it's no longer working as a Fusion Drive." This is the case with my Mac.
The article goes on to say:
- Choose Apple () menu > About This Mac, then click Storage.
- If you see a drive labeled Fusion Drive, your Fusion Drive is working and this article doesn't apply to you.
- If you have a Fusion Drive that has been split, you should see two drives. One of them should be labeled Flash Storage, with a capacity of 24GB, 32GB, or 128GB. The other should be at least 1TB.
which is also the case with my iMac
It goes on to say that this can be fixed by following these steps:
- Turn on your Mac, then immediately press and hold Command-R to start up from macOS Recovery. Release the keys when you see the Apple logo or spinning globe.
- When you see the macOS Utilities window, choose Utilities > Terminal from the menu bar.
- Type diskutil resetFusion in the Terminal window, then press Return.
- Type Yes (with a capital Y) when prompted, then press Return.
Only ...
Terminal comes back telling me that I have no SSD
I can't make head or tail of this and my iMac is so slow I could kick it's teeth in :-(
Can anyone shed some light on this?
