Hi everyone, I'm having problems opening PDF files on my NAS shares. I use MacOS and through the Finder, I access the shares of the NAS.

If I open a PDF file directly from the folder, I don't understand under what conditions, some of these open both in Mac preview and as files, incorrectly, with bugs in the display.

 

I leave you some screenshots below.

In reality these files are not corrupted as if I copy and paste the file on the Mac Desktop, it opens correctly. Even via Nextcloud from the web, the file can be seen correctly.

 

What could it be?
Thanks in advance!

Hi @Logikamente i‘m on Unraid 6.11.4 and MacOS 13.0.1. I quickly tested different shares and pdf files with no issue like yours.

Hi @cz13 I still have the problem. I put another example. I've just opened a pdf file in preview directly from the share on my Mac.
On Windows PC, however, there are no problems.

How are your SMB settings? Because in my opinion at this point this is the only problem.

On Unraid:

On MacOS all default

Hi @cz13 thanks for the config. My are the same.

I have tested and tried various possible solutions and hypotheses. I've noticed that the glitchy files issue only happens when I try to open files of about 1MB and above. All the smaller files, therefore in KB, have no problems opening or previewing on the Mac. Do you know if there are any limitations of Samba or the unraid share configuration?

No, sorry.

Maybe there is somthing helpfull like clean the quicklook cache

I tried clearing the quicklook cache, but the problem didn't go away. In any case, I don't see it only with the preview, but also by directly opening the file from the NAS share. So it's something inside the Unraid configuration or SAMBA.
Do you have any suggestions?
