Plex server in Mac won't start

When I click to open Plex Media Serve the logo flashes on the top menubar, but then goes away. I tried to do a complete uninstall and fresh reinstall because I saw from my Google searches that that worked for some people, but the problem still arises. Any thoughts on how to fix this?

Localhost page is also blank.

If the Plex Media Server won’t start and doesn’t even get to the stage where it’ll be writing to the server logs, you can attempt the following procedure to see if there’s any error messages on the OS level:

  1. Open Finder and navigate to /Applications
  2. Select Show Content from the context menu of the Plex Media Server.app item
  3. Navigate to Contents/MacOS
  4. Open the Terminal app
  5. Drag the Plex Media Server executable from the Finder window (#3) into the Terminal Window and press Return to execute it

This is no different from running the app, so it won’t succeed – but you should get a more specific error message about what’s causing it to fail starting.

Didn’t work. I get this error when I tried with your instructions. Error: Unable to set up server: sqlite3_statement_backend::loadOne: database disk image is malformed (N4soci10soci_errorE)

My guess is corrupt Database. This was working just FINE until I updated to the latest release. 1.26.0.5715. I was previously on 1.25.8.5663 and everything was just fine. Do the PEOPLE at PLEX DO ANY QA before release? Enough with the Agile Method of releases. The more functionality they put in the more Problems arise. If you ASK the majority of the PLEX Premium users all WE WANT IS STABILITY AND SIMPLICITY.

Now you know the database got corrupted and can attempt to repair it.

Side note: this isn’t necessarily about the server update but could happen if the server gets interrupted while writing to the database (e.g. power down while it’s updating the database schema after you installed the update).

I agree but either way their should be a simple way of repair the database.

I am having a similar issue. My database is blank after the update. I have tried restoring back two other backups of my database and both show up as blank.

Restoring back to version 1.25.9.5721 and then restoring my database worked for me too.

I just delete the Database and started from scratch. Not the first time this is happened. Regardless what Plex tells you this ALWAYS happens with an Upgrade. you could upgrade every time and it will happen during one of those upgrades. You could leave your version and bypassing 3.4.5 new upgrades and on the 6th it will happen. New Code seems to corrupt the Database someway.

I’m also having a crash on server startup on Mac OS 10.13.6 (High Sierra) and the 1.26.0.5715-8cf78dab3 Plex Build. Error is below. Any idea what’s going on here? Really frustrating.

I also have this issue Mac Mini 2018 - MacOSMonterey 12.3.1

Updated from 1.25.9.5721 to 1.26.1.5762 Plex gets stuck on “Server is Starting”
this happened on previous 1.26.0.5715 release also
Copied back previous content of 1.25.9.5721 and it works fine again.

Have done an optimize database other than taking a long time to run it came back with a green tick. Presumably this wouldn’t work if the DB was corrupt?

Also have Plex on Mac Mini Mid2011 - Mac OS Catalina 10.15.7 and this updated perfectly.
