About This Mac - Storage (1,42 TB available of 2TB)

Path Finder: 712,6 GB available

Finder: 799,48 GB available.

What kind of mess this ? What is the real storage and empty space on my 2TB MBP 16''2019 ??

I looked at each folder:

Applications: 27,6 GB
Desktop: 4,19 GB
Documents: 7,7 GB
Downloads: 26,44 GB
Pictures: 405,1 GB
Movies: 22,74 GB
Music: 9,37 GB

that's all. It gives 503 GB total (plus some system files). So how those Finder and Path Finder get to such nonsense numbers ?
 
Looking at the disk utility, it makes even less sense: 2 HDD there ?? What is Macintosh HD and Macintosh HD Data ??

everyday I advise new MacBooks owners to not to fret over the "other" on the apple community forums.
this is not the case because of the 82GB differential.
if you could go to "about this mac" there is a section that states what exactly is stored on the MacBook in better detail which might be info apple did not read at first like cache
You could have GB from cache from google or something related to the emails.
apple OSX does a good job of letting you know what is on your drive to the megabite.
obviously you have a better grasp of the storage situation compared to the apple community forum users
and hopefully someone else here will add vital info i might have forgot to type now.
 
This is not "GB" but 700 GB difference that is quite a lot ...
 
Well , it does not seem to be a point of some small cleaning etc. But the question is - why 2 HDD are shown in Disk Utility (Macintosh HD and Macintosh HDD data) ?? Macintosh HD: used 11,26 GB and available 713 GB ??? What is this ? There is just one HDD inside: SSD 2TB, nothing else

This may shed some light on what you're seeing:

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.

Your total available storage space is about 1.4TB as reported. 700GB is now used as cache for something else.

As for the extra "data" volume, that's because MacOS now stores OS-related system files on a separate volume and it locks that volume down. Both volumes are then "combined" into a "container" (partition) such that you still see just one drive with all of the files available like before, but system files are no longer modifiable. Also, the amount of storage space (free or not) is shown for the entirety of the container.


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).

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.
 
Hmm, interesting , but isn't this approach a kind of user super messy and confusing ? As a user, I want to know just what is the free and (really) occupied storage on my disc. That's all. Why to make such an unpractical mess in it ?

In my experience, About This Mac seems to give accurate results as to how much you can actually use, while Finder often gives pure fiction (once telling me I had 1.4 TB free on a 1 TB SSD).

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 ?
 
Yeah, Finder no longer gives the right amount of space available. I suspect it's because it's adhering to legacy behavior (not taking into account purgeable data), whereas Apple has changed their file system a lot over the years.

You should trust "About this Mac" more. Personally, I use iStats to keep track of everything, including disk space, and it's fairly accurate.
 
Disk Utility explains your "mystery" perfectly. See where I circled the answer.

Your files live on the Data volume. On that volume, you have 1.43TB of available space, 712.66GB of which is purgeable data, and the remainder is free space. Both Finder and Pathfinder are only reporting the free space. The difference between Finder's 712GB and PathFinder's 799GB is probably due to how they define GB (like how hard drives report GB as 1 billion bytes while to some software a GB is 2^9 bytes).
