    Hi, thanks for reaching out to our forum.

    Could you share a few details to help us investigate?

    - What version of DAR are you using, and what version of macOS?
    - DAR crash logs (Navigate to Help > Export Logs, and attach the exported log file here)
    - What are your session's sample rate and frame rate settings?
    - Does the error appear immediately when you start the export, or does it happen partway through?
    - Does it fail every time, or only intermittently?
    - Have you ever successfully exported this same session to MP4 before?

    If you haven't already, it may be worth updating to the latest version of DAR:     https://customer.dolby.com/content-creation-and-delivery/dolby-atmos-renderer-v550/

    Best,

    Thanks so much for sending over your .atmos file package.

    I tested your files on my end and was able to export to MP4 without any issues, so the problem appears to be specific to your system rather than the session itself.

    Could you please share your DAR logs? In DAR, go to Help > Export Logs and attach the exported log file here.

    In the meantime, this could be related to file and folder permissions. Please navigate to System Settings > Privacy & Security > Files & Folders and confirm that Dolby Atmos Renderer has access enabled.

    To verify, go to Applications in Finder and right‑click the Dolby Atmos Renderer Application, select Get Info, and make sure your user account has Read & Write access. I have attached the screenshot for your reference.

    Best,

    I have the same issue since switching to Mac Studio M5 pre loaded with MacOS27, I am still troubleshooting. It might be worth looking at your Privacy settings as an initial check to see if full access has been granted to the renderer. I hope get it sorted, if I do I will let you know.

    Hi My Mac just updated to MacOS27 and it doesnt export in .mp4. I dont know what to do I have clients that are waiting to receive Dolby Atmos files. Can you forward an update obviously the new MacOS is not compatible with version 5.5.

      Hi,

      Sorry that you are experiencing this issue. I have shared the information with the team for further investigation. Have you already tried checking your file and folder permissions?

        Everything is perfect all our Macs did the update and your software doesnt work. Even the Media encoder doesnt load up on all our computers. We need help this is our job. Thank you very much.

        Hello. I have attached a picture of the problem. I hope you can fix it. Obviously you need to update the software. Thank you for your help.

        Thank you for following up. We still need your DAR logs: Navigate to Help > Export Logs, and please attach the exported log file here.
