After the replace from Mojave to Catalina I observed that the used disk area has elevated from about 1TB to nearly 2TB. And there’s hardly any free disk area left.
A more in-depth inspection of the file construction of the entire system reveals that about half of the information is within the folder
/System/Volumes/Information/Earlier Content material/Customers/myusername. It appears to be a mirror of my person information that was created through the improve. This may clarify the sudden doubling of the disk area used.
I am unable to discover any clear details about the aim of the folder
/System/Volumes/Information/Earlier Content material/Customers/ neither right here within the discussion board nor on the internet. Is it potential that after upgrading and establishing all person information from the backup, the contents of the folder
/System/Volumes/Information/Earlier Content material/Customers/ may be deleted with out issues? Because it doesn’t appear to be mandatory for the operation of Catalina?
(Observe: this query is not in regards to the basic goal of the APFS partition
/System/Volumes/Information/ of the brand new APFS)
