Description of Issue

I just migrated to new mac studio from iMac. The iMac is now retired. The new mac studio found the iMac core and after downloading and installing the new Roon app, I changed the name of core from iMac to mac studio and it cannot find any players or applets, speakers etc. What have I done wrong - how do i fix?

Maybe I’m misunderstanding, but to me it sounds as if:

• You hard your iMac running as a core
• You installed Roon on your new Mac Studio, where you went to Settings > Setup and changed the “Core name”
• You then retired your old iMac

I f this is indeed the case, then you did nothing more then change the name of the core running on your iMac. As a result, retiring your iMac would remove the core from the network, which could explain what you are seeing.

For a step by step guide on moving the core to a new machine, please refer to

I just migrated to new mac studio from iMac.

Using an Apple migration tool to move Roon can cause failures. As noted in this post:

Migration Assistant successful from MacMini to M1 MacMini, Now what?

@KURT_SMITH, welcome to the Community. Just a fellow user here, but Roon cannot be migrated from one Mac to another using Apple’s Migration Assistant. Is your 2014 Mac mini still available from which to make a backup of your database from within Roon? If so, I believe you will need to delete Roon from your M1 mini and follow the guidelines below on migrating your Core to the M1 mini:

The steps to move Roon is detailed in this thread

Try uninstalling Roon completely on the new Mac*. Download the latest from Roon and install that. Then restore a backup.

*There maybe hidden files that you need to manually delete, see this post…

Help needed removing Roon Core artifacts from iMac

Have you removed Roon from the Applications folder? If not, open Finder and click on the iMac under Locations, then navigate to macOS, followed by Applications. Right-click on the Roon icon, and select Move to Bin. Next, go to the Finder Go menu, and select Library. Now delete the Roon and RAAT folders. This should have completely removed Roon. Kindly note that this is irreversible, so be certain you want to take this action. It may be necessary to restart the iMac.

As always “good” backups are need prior to doing this stuff. And by “good”, a backup that has been tested using a restore.
