This volume is not formatted as APFS

I am unable to install Catalina. I'm currently running Mojave 10.14.1. When I try to install Catalina it says "This volume is not formatted as APFS"

What should I do?


Thanks!

If you are seeing this screen with a padlock



then you have an EFI firmware password set which can be different than your user account password. If you don't recall the password, then you will need to provide valid proof of purchase to Apple to that Apple can remove the firmware lock. See this Apple article for more details:

If this is not the issue, then try booting into Internet Recovery Mode using Command + Option + R. Otherwise we will need more information on exactly where you are seeing the need to unlock the system. Maybe provide a picture.
