I didn't ever notice this unti I updated to B4 via OTA. Under About Mac Storage in now see a section the used to say purgable but now after the upgrade I see Used Space and Other Volumes in Container. Is this the norm now? Is that part of the APFS container? Maybe like the preboot and recovery volumes? Is this something I can gain back the storage space from?
I tried to post a screenshot but can't seem to do that.
