Adding an APFS (Monterey) Volume to my Big Sur iMac?
I need Monterey to access all the new features in FCP X but I don't want to get rid of Big Sur. So I intend to create a new volume on my iMac's Fusion Drive.
The Apple Support instructions state . . .
"In the sidebar, select your existing APFS volume, such as Macintosh HD."
I have lots of drive items listed below "Fusion Drive" (which will apparently work) so should I choose Macintosh HD? Is this the best option?
