My 15 inch MacBook Pro mid-2014 is stuck on Mojave 10.14.1 apparently because my drive is HFS-formatted. When I try to install the Update I'm told that I can only install macOS on APFS drives. Is there any way I can fix this problem? I don't want to try reformatting my Mac HDD without expert advice that it's ok to do that. Meanwhile, there are security risks staying on 10.14.1 so I want to resolve this as soon as possible.
