macOS SMB problem 100039

Operating System ZimaOS
1

Hi, I’m new to the ZimaOS environment — I’ve been using it for just a few weeks.
I’m experiencing a small issue with SMB sharing and macOS.

I have a mini PC with an external HDD connected via USB. I’m sharing both a folder on the internal drive and one on the USB drive.
The problem occurs on macOS: when I copy files to the shared folder on the internal drive, everything works fine.
But when I try to copy files to the shared folder on the USB drive, I get error 100039 and the operation fails.
On Windows, everything works without issues.

Has anyone else encountered this problem and found a solution?

I searched for similar issues on Apple’s forum. It seems to be a macOS-related issue.

For now, you can use the alternative method instead. (For example, to internal drive first, to USB second)
