Description of issue:

Hi guys,

Apologies in advance if I’m a little vague and lacking technical terms throughout my description of issues here, I’ve spent hours reading through posts and doing my best to grasp the terminology but am openly in a little over my head!

Issue in a nutshell:

  • Upgraded my Mac mini to Catalina OS, which I’ve used for a few years as a data hub at home without any issue. SABnzbd / Sonarr / Plex. Since the upgrade to Catalina, encountered issues with my external HD, which eventually led me to replacing external HD. Encountered issues listing the new HD as the path folder, and read an article suggesting uninstall/reinstall Sonarr as a potential easy fix. Followed this article to do so: How to uninstall sonarr on MAC

  • Downloaded Sonarr after following uninstall instructions, but faced ‘The application Sonarr can’t be opened’. (have tried v2 and v3)

  • Most articles I read refer back to the config/NZBDrone folder - this is missing for me. I don’t have any reference to NzbDrone on my Mac mini at all, and therefore can’t track down log files etc which I see referenced in a lot of trouble shooting pages. No backup etc for these folders either (likely cleared in one of my many hopeless attempts to get it working again).

Any basic trouble shooting steps or links to same issue would be greatly appreciated.

Thanks in advance!

Justin

I had the same issue; but the fix is pretty simple.

It turns out for whatever reason the Sonarr bootstrap script wasn’t actually marked as executable when the app bundle was built. Assuming the Sonarr app you downloaded has been moved to the Applications folder, run the line:

chmod +x /Applications/Sonarr.app/Contents/MacOS/Sonarr

Oh wow - you’re right that fixed it instantly! Thanks so much for your help :slight_smile:

Thank you, thank you, thank you. This fixed my problem and I have been reading forums for days on end. Thank you.

Thanks man been racking my brains for days it worked right away

open Terminal and run command which ever one is relevant to the app your getting to run in OS Catalina Then your App will open up and run…

chmod +x /Applications/Radarr.app/Contents/MacOS/Radarr

chmod +x /Applications/Sonarr.app/Contents/MacOS/Sonarr

It has not worked for me, I no longer have the message that “I cannot open the app”, but it is frozen and although it appears as Sonarr is open it but does not open anything and the only way out is to force the exit.
