Why Is My Saying Could Not Create A Preboot Volume For Apfs Password Or Erase

They were cloning drives with macOS Catalina, but their cloning process was not including the Recovery volume.

Was there a way to create a new Recovery volume on a macOS Catalina boot drive that didnt have one.

The script was downloading and expanding a macOSUpd10.13.6.RecoveryHDUpdate.pkg installer package from Apples Software Update service in order to get access to a dm tool included with the installer package.

This installer package was no longer available from the Software Update service, but a similar package named SecUpd2019-005HighSierra.RecoveryHDUpdate.pkg with the same dm tool was available.

I assume you are not talking about cloning an entire image but something else.

In my testing, both local recovery mode and internet recovery mode only give you the option to Reset a users password or erase the drive.

Once FileVault has been disabled or the Drive is erased we are then able to boot back into recovery mode (Internet recovery mode if the drive was erased) to reinstall the OS.

It adds an extra step to rebuilding Macs that are reclaimed and getting ready for re-deployment.

Hopefully I am missing something and there is a better way to do this for Catalina.

I tried installing the Mojave recovery partition using this script after the Catalina version gave me the circle-slash upon recovery startup (OS too new for this computer, circle-slash and shutdown).

THANK YOU for a fantastic solution to a rather obscure problem.

I also had to use gdisk to repair bootcamp hybrid MBR after, not sure why.

Im on Mojave 10.14.6.

After installing and deleting big sur on my internal ssd (its installed other partition than Mojave), my mojave recovery partition was deleted.

I tried this script, but it couldt identify my target disk and failed.

Downloading SecUpd2020-003HighSierra.RecoveryHDUpdate.pkg into privatetmp 100,0 Failed to create 10.14.6 Recovery partition on.

I dont know what to do My MacBook came with Mojave, I upgraded to Catalina, and after downgraded to Mojave, and now I cant enter in Recovery Mode.

When I try to enter, it starts downloading something for 5 minutes and then fails.
