I installed a clean copy of Mojave and it is formatted as APFS. When I tried to upgrade to Catalina I got the error "Could Not Create a Preboot Volume for APFS". Does this mean I made a mistake by choosing that format? If so is there any remedy that doesn't involve yet another full clean instal? I do have a time machine back up can I instal that oil a reformatted drive?
I found this:Could Not Create a Preboot Volume for APFS
The “could not create preboot volume” along with other APFS (Apple File System) errors associated with converting an HFS+ drive to APFS are rarely encountered, an indication of the maturing of the APFS file system.
macOS Catalina requires the use of APFS instead of HFS+. If you’re upgrading from an earlier version of the Mac OS and you were using HFS+, the installer will convert your target drive from HFS+ to APFS. This, in itself, is not an issue. However, in rare occurrences, you may see an error message.
If you encounter this issue, the cure is easy enough: you just need to erase the target drive using Disk Utility. If the target drive was your startup drive, you’ll need to boot into Recovery mode to access Disk Utility. You may also need to restore your Mac’s data using a recent backup before restarting the installation process.
It doesn't say what format to choose when erasing the target drive?
TY in advance!
