I am wondering if you have two related-but-not-identical issues - On the Mac, I’m not sure if automatic scanning of network shares works. If it does, it also relies on support from the NAS. (I’m not optimistic. I suspect it would require a different mechanism + polling. Maybe somebody can speak up.) And on the NAS - what is the NAS, by the way? Synology? - you might be running into a limitation with the maximum number of directories that can be monitored automatically. Generic Linux, plus some background information: [https://forums.plex.tv/t/increase-the-number-of-directories-linux-can-monitor-notify/209156](https://forums.plex.tv/t/increase-the-number-of-directories-linux-can-monitor-notify/209156) If Synology: > [@Synology FAQ - Questions, Answers, and How-To's](https://forums.plex.tv/t/synology-faq-questions-answers-and-a-few-how-tos/490215/22): > > FAQ 16: Increase the number of folders Plex can monitor Applicable to all supported versions of DSM. When the Linux ‘inotify’ table fills up, this will cause when Plex to stop automatically detecting new media you add to the server. It will also manifest when there are transcoder problems with Dolby audio codecs. Linux has a default table size which is static. We can increase this at will. On some versions it’s 8192. On newer kernels, the default is 65536 folders. This is easy to incr… Either way, it’s worth following those instructions to identify how many directories are in use, and if applying this fix would be worthwhile. --- _[View the full topic](https://forums.plex.tv/t/pesky-bug-with-auto-content-scanning/661421)._
