Apple discontinued support for classic HFS (also known as Mac OS Standard) volumes in MacOS 10.15 Catalina. As a result, Macs running the latest version of MacOS cannot mount volumes created on vintage machines — such as those running Mac OS 8 and Mac OS 9.

Officially Apple discontinued support of HFS in 10.12 Sierra
