What kind of mess this ? What is the real storage and empty space on my 2TB MBP 16''2019 ??
Amount of space available, which can include both free space and “purgeable space”—or space that macOS can free up when needed by removing files from your computer. You can’t manually remove the files that are designated purgeable, but macOS removes them as space is required.
Apple File System (APFS) allocates disk space on demand. When a single APFS container (partition) has multiple volumes, the container’s free space is shared and can be allocated to any of the individual volumes as needed. Each volume uses only part of the overall container, so the available space is the total size of the container, minus the size of all volumes in the container.
On your computer, macOS is installed on a set of volumes known as a volume group. The volume group consists of one volume used for the system files (named Macintosh HD) and another volume used for data (named Macintosh HD - Data).
So it means I should not worry and any 700 GB limitation and I have really 1,4 TB free space that can be filled without any problem ?TL;DR: your disk is 2TB, about 700GB is currently in use to store "hard" data such as your personal files and system files. 700GB is purgeable cache that MacOS will free up as needed.
Yes. Like I said, (and @Nermal as well) go by what "About this Mac" states.So it means I should not worry and any 700 GB limitation and I have really 1,4 TB free space that can be filled without any problem ?
