Upgrading from High Sierra to Mojave but retaining HFS+ file systems
I have late 2012 iMac 27" (core i7, 32GB Ram, 2GB Graphics) that has a Fusion drive AND an external drive box that doesn't support conversion to APFS. Can I upgrade to Mojave and use HFS+ file system or do I have to wait until I nix the Fusion drive AND/Or upgrade the external HD box??
