When the installer shows me the drives to install, I get grayed out 500GB Windows 10 Bootcamp and 2,61TB macOS High Sierra. It's normal for Bootcamp to be grayed out but the macOS partition is also grayed out with a note telling me that I need to delete Bootcamp partition to install Mojave PB on it. Anyone else having this issue? Is it because of the relatively new APFS file system maybe? It there a workaround ?
