Core Storage

Core Storage is a logical volume management system on macOS that was introduced by Apple to Mac OS X Lion.

Core Storage is a layer between the disk partition and the file system.

Apple CoreStorage defines four types of objects, instances of which are uniquely represented by a UUID: Apple's current implementation is not intended for the traditional roles that LVMs were/are used for.

Core Storage also doesn't support thin provisioning, different RAID levels or resiliency.

However, like in Linux, but unlike in Windows, the LVM can be used as the root filesystem, a significant advantage for home users who prefer to have a single volume for the OS and storage or find the need to extend the amount of storage available to the core operating system.
