Hi! What’s not quite right with Roon?

· Roon is slow, freezing or won’t start

Roon is slow, freezing or won’t start

· Roon won’t start up at all

Tell us what's going on

· Roon won't start on my Mac Studio

When clicking the icon in my dock on my Mac Studio M1 Ultra (running Tahoe 26.4) the app icon bounces twice and then never opens.

I updated to the latest Roon on April 7, 2026 (not sure what version number this is)

By way of a follow up:
Weirdly when I opened up various folders in the App, I found that my Dark Theme (the theme I use) folder was empty?

copy pasting the theme files back into the folder fixed it… not sure why they disappeared in the first place.

Hi @Ben_Thompson,

Thank you for your post.

A few things you can check if this recurs:

First, retoggle Roon’s local network permissions under Privacy & Settings in MacOS System Settings. New updates tend to cause Tahoe’s more sensitive security settings to panic and restrict third-party app’s network permissions.

If that doesn’t help, you can always reinstall the GUI itself (which will automatically replace any missing theme folders):

Let’s try a fresh database and see if your issues persist:

  • Exit out of Roon + RoonServer (from menu bar or Activity Monitor)
  • Navigate to your Roon Database Location
  • Find the “Roon” folder and delete it. Don’t touch the RoonServer folder!
  • Reinstall the Roon App from our Downloads Page to generate a new Roon folder
  • Open Roon again

We’re glad to hear your issue was resolved in the meantime without these steps. Happy listening.
