MacOS 27 Golden Gate issues

Plex Media Server
1

Server Version#: 1.43.4.10903
Player Version#: 4.160.0
After upgrading my M1 Mac mini to MacOS 27, Plex says that some of my TV shows are missing. It only happens with TV shows that have accents in their filenames, like “Anatomía de un instante”.

I’m connecting using SMB to a Synology NAS. Files are OK, in Finder, in terminal, and in Synology File Station. I am attaching the logs. And some screenshots.

Maybe Plex Files Unavailable but they’re not missing - #740 by Anyware

No, just because it only happens with files with accents, without them it does not happens. Are different issues. If I rename the files name without accent, it appears again. For example:

If I remove the from file’s name, after a library scan:

Then either your NAS is using a wrong text encoding schema, or the Mac has some bug in its SMB client.
I’m not an expert in either of them, it is just a direction for further investigation.

The curious thing about all this is that both the Mac and the Synology correctly recognize the file with accents; only Plex says it can’t find it. It only happens with accents; it doesn’t happen with other special characters.

With the following entry in /etc/nsmb.conf:

dir_cache_off=yes

All files are back. So it seems that is something wrong in MacOS directory caching…
