Mmm... you're talking about this, right?

>>> psutil.disk_usage('/Volumes/AUTODOWNLOAD')

That looks like a precision issue. Point is psutil uses os.statvfs() in
order to determine disk usage so the problem should originate from that
(hence it's "Python's fault" hehe).

Can you paste the output of "import os;
print(os.statvfs('/Volumes/AUTODOWNLOAD'))"?

Problem is f_bavail (available size) which is way higher than f_blocks
(total size), and that of course doesn't make sense.
I guess os.statvfs() just doesn't work well with SMB filesystems.

It works fine on my rpi againste the same share. Seems to be a osx issue,
I'll see if I can tried a older osx version and try there. At least the
free size is correct :p

The problem only accures with osx against a unraid share (ntfs). The size
is correct if i mount a physical drive.

Yep, I'd be keen on assuming this is an OSX bug. I guess the best we can do
is to signal this in the doc.

I will assume this is an OSX bug and close this issue.
