Apple's APFS is still a work in process! Fusion Drives & RAID are still not supported yet. ![]() In fact if you have a SATA SSD you're better off staying with GUID & Mac OS Extended (Journaled) for now as APFS has issues with queuing across a SATA interface (not an issue with PCIe SSD's). You encounter time-points when you are saving a snippet, URL link or a file and the system will pause the action, yet the process you are running won't have any problems. I've see it take almost 30 sec for the file to show up on the desktop! Yet, if you do the same thing running the same actions on a PCIe SSD it won't stall-out. Today I tried all the options to create a APFS RAID with no luck. I made a backup of my data, Erased my RAID with diskutil in Terminal, Created a new RAID in RAID Assistant, the only Format option was Mac OS Extended no APFS option here, Erased the new RAID volume in Disk Utility and created a APFS volume, Next I tried to install Mac OS High Sierra, the installer allowed to chose the new APFS RAID volume and the installation starts normally but in the end (aprox 8 min) the installer gives an error: 'Could not create preboot volume for APFS install'. You can see disk2s2 in the screenshot below, the partition on my external hard drive hosting the APFS Container. Below that, /dev/disk3 is the APFS container, and /dev/disk3s1 is the APFS volume. Sep 26, 2017 - 1 Hello guys i have just installed high sierra and this happen. When i put my. My advice still stands, use your backup and then try reinstalling High Sierra. Message could not create a preboot volume for APFS install WTF. Tried using diskutil instead of Disk Utility and a new updated High Sierra download but the results ware always the same. I ended up doing a rollback to my Mac OS Sierra backup. The issue is APFS specific. So your options are: 1. ![]() Clean Install: Install to a standalone drive (separate from your SSDs), then use Disk Util to create or format your two SSDs RAID 0 and make sure it is formatted Journaled HFS+. Then clone the single drive to the RAID 0 volume and it will work. I had tried this method using APFS on the RAID and it fails to boot. So the issue is APFS *can't* boot from RAID. You can try upgrading to High Sierra, but without converting the file system to APFS. (I have not tried this myself). Download High Sierra, but do not install it, then from the command line run: /Applications/Install macOS High Sierra.app/Contents/Resources/startosinstall --converttoapfs NO --volume /DestinationDriveName. Use to clone a disk with High Sierra to the RAID volume. You cannot install High Sierra directly to a RAID volume. However, if you use (which is free for this, btw) you can simply copy/clone the drive with the working High Sierra over to your RAID volume. Some important points: • When you create your RAID volume, make sure it is in Mac OS Extended and not APFS. • You can actually be booted up in the High Sierra install that you’re intending to copy _from_ when you do this. I’ve done this and it works great.
