Factory reset all settings on Plex server macOS?

Plex Media Server

Server Version#:BETA
Player Version#:ALL

I’m running Plex Server on a mac mini to record and stream TV from my HD Homerun. I watch and record live TV on the mac mini as well as stream to an appleTV and Android device.

I allowed Plex server on my macOS to update to the Beta release. After the update all Live TV streaming was broken with the video being all broken/garbled. I deleted Plex server and re-installed the most recent public release but all Live TV video is still unwatchable from any device. I deleted Plex Server again and re-installed a version from June 2025. Pleax Server now allows me to stream Live TV to all devices. The problem now is that all new TV recordings are broken up and garbled video with sound intact. To me it looks like a video encoding issue. I’ve tried changing multiple transcoder settings to get things to work but no joy. I even tried updating to macOS Tahoe but that hasn’t fixed anything.

Question1: How to I “factory reset” all the settings on Plex Server? Where are all the Plex settings buried on the macOS system?

Question2:How do I delete ALL Plex installations and purge ALL Plex settings on my macOS device so I can do a clean install from scratch?

You should also remove any outdated server entries from Authorized Devices.

The Plex Data Folder contains the database files (../Plug-in Support/Databases) which contain the library definitions, etc.

If you delete the database files, then you will have an empty server.

~/Library/Preferences/com.plexapp.plexmediaserver.plist stores various settings such as which port to use for remote access, number of log files to keep, etc. It also contains settings that uniquely identify your server to Plex (machine id, etc.). If you delete this file you will need to re-claim the server. You should also delete the server from Authorized Devices.

To find the plist file, use the Finder’s “Go” menu, select “Go to Folder” and enter ~/Library/Preferences. Reference: Advanced, Hidden Server Settings.
