My Macintosh HD is running Sierra from which partition for Mojave was made which doesn’t has APFS option.

Installed Mojave 10.14.2 on a MacBook Pro mid 2012 which has HDD and volume formatted in macOS Extended Journaled.

Tried to install Xcode 10.2 on Mojave 10.14.2 and got error "this version of Xcode requires Mojave 10.14.3 or later"

Then downloaded macOS Mojave 10.14.4 Combo Update, tried to install it and I got an error:

How to convert the Mojave volume from macOS Extended Journaled to APFS even when convert to APFS option is dimmed in Disk Utility:

    I'm on Mojave 10.14.1 and booted into recovery mode. I don't even see the "Convert to APFS" option under Edit menu, and the boot volume is grayed out.

As far as I know it is not possible to convert an macOS Extended Journaled drive to APFS without losing data.

The only way I was able to install a newer operating system was to backup the drive with time machine, fresh install the new operating system (catalina), migrate data from the time machine backup after install.
