I’m running Roon 1.7( 667) on an iMac 2019 + Big Sur 11.0.1.
I get a FATAL ERROR occasionally when starting Roon.
Hi @ucchi — Just to confirm, this doesn’t happen every time? Have you noticed any patterns in when this seems to happen?
It doesn’t happen every time; it seems to happen most of the time right after the OS reboot.
Hi @ucchi,
The next time you see this happen please make a note of the time it occurred and use the directions found here and send us over a set of logs using a shared Dropbox link. We’ll take a closer look!
@dylan San
The problem has happned. After rebooting the OS, Roon had no problems and failed on the second Roon Start. I’ve placed the Log at the iCloud link.

Hi @ucchi,
I just wanted to let you know the team is looking into this and I’ll be sure to follow up as soon as I have their feedback.
In the meantime, can you elaborate a bit on exactly what happened here? Was this a device that was previously running Roon without issue and this started occurring after the macOS update or is this a new device?
@dylan san
The same device. (iMac 2019)
Occurred after the update to Big Sur.
I thought it might be a permissions issue and yesterday I had First Aid run on the system disk.
Thanks, @ucchi. I’m reviewing with the team and will get back to you ASAP.
Hi @ucchi,
Can you try uninstalling the app and reinstalling and let us know if you continue to see this error?
@dylan san
Thanks for the advice.
Since I had First Aid run on the system disk 10 days ago, the problem has not reproduced. I will try to reinstall it next time when the problem occurs.

Hi @ucchi, I’m having exactly the same problem as you. I have reported the issue, but what is this ‘First Aid’ you mentioned.
Hi @mikeb, found it, thank you. Ran it this morning, no errors reported.

I’m getting the same issue, on a 2017 iMac running Big Sur 11.1. I’ve downloaded the installer and reinstalled. It launched once after the install, but second time gives the Win32 IO error mentioned above. Trying to launch again gives a different error: “Object Reference not set to and instance of an object.”
Hi- another mac user here. I am running Roon Core 1.7 (build 710) on my Mac Mini with Catalina 10.15.7 on my Mac Mini and laptops. I haven’t updated yet to Big Sur.
How has your experience been lately with Big Sur and Roon?
Interestingly, one of the suggestions in one of the several threads suggested “rebooting again” which so far seems to have resolved it. After reinstalling Roon 1.7, it worked. After a reboot, it gave the error again, but after rebooting a second time it has been working fine for at least a couple of hours… I haven’t had any other issues with Big Sur 11.01 or 11.1.
