Plex Desktop App Not Opening on new MacOS Sequoia

Hey, I haven’t been able to use the Plex desktop app, since I recently deleted and re-downloaded the app for MacOS.

Context, I’ve recently downloaded the Beta test version of MacOS Sequoia (new MacOS) - however, I believe this is a separate issue.

If the Plex app won’t start and isn’t showing any error messages, 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.app item
  3. Navigate to Contents/MacOS
  4. Open the Terminal app
  5. Drag the Plex 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.

Edit:
One additional question: are you running the Plex app on an Intel or M-series Mac?

It‘s a maOS beta… so there can be all kinds of issues.

I would try to completely uninstall Plex for Mac, reboot, then install it again.
Because I do that a lot for testing, I have a script I call delplex.sh

#!/bin/bash

echo ' '
rm -rf /Applications/Plex.app && echo '[1/5] deleted the app'
rm -f ~/Library/Preferences/tv.plex.desktop.plist && echo '[2/5] deleted the plist'
rm -rf ~/Library/Logs/Plex && echo '[3/5] deleted the logs'
rm -rf ~/Library/Caches/Plex && rm -rf ~/Library/Caches/tv.plex.desktop && echo '[4/5] deleted the caches'
rm -rf ~/Library/Application\ Support/Plex && echo '[5/5] deleted the application support'
echo 'Plex for Mac has been removed.'
echo ' '

You’re an absolute legend. Fixed!
