FIX- Could not create a Preboot Volume for APFS install

Right Mac users. If your facing the same problem like me then I suggest you listen up. First don't try to install Mac OS high Sierra again or try anything else. You want to first of delete your drive until you have no drive. Yes I mean no drive. To do this, power off your Mac and then hold command + R and boot up your Mac. This should do the trick. Then delete your drive in disk utility by clicking the minus button on the top right and then enter internet recovery mode by repeating the process though this time adding option and then command + R. Then you will enter the same menu which is mac os utilities and then this time instead of Mac OS High Sierra you will just see Sierra. Go disk utilty and create a disk this time clicking + and make a drive calling it Macintosh HD with the format Mac OS Extended. The fix is your removing the APFS system which is what is confusing the drive which for some reason apple can't figure out them self. Then just click install Mac OS and you should be good to go. Hope your all good and ask anything you need.

MacBook Pro (13-inch, Late 2016, 4 TBT3), macOS High Sierra (10.13)

Hello, I have tried to erase it and it fails. It’s details say “the volume ‘recovery’ on disks3 couldn’t be uncounted because it’s in use by process 0 (kernel)

Couldn’t unmount disk.

Operation failed...” do you know what this means, how to fix it and what I should do next?

Yes, but most of its just dragging the files into Terminal. Just watch the video and pause at each step. You will get it....



Other videos actually have you typing all the commands into terminal.... Now that is a pain..... lol

Hello Ethoic,


I believe that your statement:


"Then you will enter the same menu which is mac os utilities and then this time instead of Mac OS High Sierra you will just see Sierra"


Should read:


"Then you will enter the same menu which is mac os utilities and then this time instead of Mac OS High Sierra you will just see the OS that your Mac originally came with when you purchased it."


I tried your procedure, and when I got to this point, instead of macOS Sierra, the OS installed was El Capitan, which installed successfully :-)


Thank you for your post! I've now successfully upgraded to High Sierra.

So have same issue on a Macbook Pro 2017. Managed to delete the Macintosh HD drive ...but on restart I can't add a new drive which seems a little fundamental to getting this fixed. On reboot I get a Container disk show up - I can't see the MAC OS Extended option only APFS which if I do I get the same issue. I can't delete the Container DIsk (no MINUS option shows). How do I get to the option to add the new drive without APFS options? Thank you!

Hello, have you tried to create a bootable thumb-drive. I believe this is a server error issue after speaking with AppleCare. The bootable thumb drive worked for me.


After upgrading to High Sierra on a laptop with SSD, Mac OS Extended Journal is no longer an option. This is only available on iMac with spinning drive.


FYI, I'm no expert......

Thank you so much for this solution. I brought my macbook air to an authorized repair shop because i was having multiple issues installing high sierra. They kept my device there for two weeks and told me they could not repair it and I would have to buy a new one!!!!! The excuse was it was just too old. Really? 2013 models are supposed to be able to perform this update. So I took a Sunday and devoted the day to fixing it myself. This is the only solution that worked for me. I am not a computer expert. Just a SAHM that refuses to be told her perfectly good computer that was working fine one minute is suddenly unusable after trying to install an update apple told me I needed.

beto153- Did you try selecting the partition tap when adding the new drive? I'm not a Mac expert, but when I went to delete the drive and add it again, I did not have the option either. I had to create a partition which I just left the same size, and then the option was available to me. Not sure if what I wrote makes sense as I can't go back now and repeat what I did.

The key step in the process of erasing the existing volume is selecting the correct type that it will be reformatted as. The first couple of times I erased it and selected the APFS type to be the new volume type and ran into the original error about not being able to create the preboot volume. The type that should be selected is "MacOS Extended (Journaled)" - once I erased to this type the install worked seamlessly.

I can't seem to edit or delete the above, but this turned out to be incorrect. The install process continued for hours, which made me think it was working, but never completed. After giving up and rebooting and trying the above method again I quickly hit the APFS install.


In the end I just made a High Sierra installer boot USB drive and used that instead and had no issues at all.
