Attached is a mapping of one of my system drives.
I have always been one to install numerous volumes on a drive to either keep old things going, or try new systems.
I’d like to keep my High Sierra, Mojave, and Monterey systems in place but add a Ventura volume as an experiment before upgrading the Monterey volume to Ventura
On this particular drive I did not create separate partitions, but multiple APFS volumes.
The sizing and free space notes still confuses me a bit … to cut to the chase I have attached screenshot and mapping of the drive.
Q1: are the old Mac OS 11.1 volumes just old Big Sur snapshots? Can they be deleted i.e. reformatted at this point?
Q2: notwithstanding the dubious nature of adding so many volumes to one drive, might, should I utilize the more capacious free space (458GB) on the Mojave “volume”
Technically I think minimum of 60GB might suffice for a Ventura volume
Anyway if anybody’s interested LMK
If not I’ll understand
My basic update is: the drive mapping was more understandable booted in HIgh Sierra, so I simply added a volume to the Container in lieu of reformatting any particular volume
I guess I will need to review the volume mapping with the Terminal
as Disk Utility does not seem to detail all the various hidden volumes.
I am having a bit of a hard time getting clarity at eclecticlight on why Big Sur
installed 3 nominal versions of itself. Per my image, Big Sur installed the main volume (which now runs Monterey, btw) and one and then another “shadow” volume. The first at the first install, and then another shadow volume at one of Big Sur’s major updates. Interestingly both tagged as
Mac OS 11.1 … That’s why I was wondering if they were Big Sur’s version of snapshots …
Simply run the command df in the terminal and you’ll see all mounted volumes and where they’re mapped from. It’s a totally safe command, you don’t risk deleting any data.
