[QUOTE="MacInWin, post: 1923593, member: 396914"] More important than what is in ~/Library, what does Disk Utility show? That tells you the drive structure and for the internal drive. Turn on the "Show all Devices" view and it should look like this: [ATTACH type="full"]37393[/ATTACH] The "Media" is the hardware level. In your case it will be the hardware of the drive itself. The "Container" line is similar to what used to be a partition, but with significant enhancements. The "Macintosh HD volumes" is a merger of the next indent level items and is what you see on the Desktop as "Macintosh HD." The greyed out "Macintosh HD" is the Secure System Volume that is signed by Apple and then encrypted. The "Macintosh HD snapshot" is the image from which you are booted and is a clone of the SSV. By not booting directly from the SSV, Apple can keep malware from making any change to the boot system. At boot time, the hash of the SSV is compared to the hash of the snapshot, and if they don't agree, the system rebuilds the snapshot from the protected SSV. The "Macintosh HD - Data" is where all user data is kept for all users you have added to the system. That is also the area you are allowed to write to as a user. Here is more detail for you: [URL unfurl="true"]https://eclecticlight.co/2022/10/25/ventura-volume-layout/[/URL] [TABLE] [TR] [TD][/TD] [TD][/TD] [TD][/TD] [/TR] [/TABLE] [/QUOTE]
